What the BBCCT 107 Solved Guess Paper Covers for Enzymes in 2026
BBCCT 107 Solved Guess Paper is a 16 question answer file for IGNOU's Enzymes course, written from the official BBCCT-107 book and mapped to all four blocks and twelve units. Each question carries a written answer, the block and unit it belongs to, the sessions in which it last appeared and a word target based on its marks. Nothing in the file is a bare heading or a bullet list you still have to expand.
The paper was prepared for the 2026 Term End Examination cycle, with the December 2026 session as the live target. It works for repeaters and for students appearing for the first time, because the question set is built on topics IGNOU keeps returning to rather than on a single session's paper.
Enzymes is a course where students lose marks in a very predictable way. They know the topic but write it as a loose paragraph without the definition, without the count the book gives and without a labelled diagram. Every answer here is shaped the way an examiner wants to read it, which is why it works better than a hurried set of notes. If you also want other courses of your programme, the full IGNOU Solved Guess Paper collection lists them by code.
Sample Questions and Answers from the BBCCT 107 Enzymes Guess Paper
Five of the 16 answers are reproduced below, one each from Block 1 and Block 4 and the rest from Block 2 and Block 3, so you can judge the writing before you enquire. These are shortened on screen. In the file each of them runs to its full marks length with the tables and diagrams intact.
Read any one of them end to end. If the language is clear to you here, the remaining 11 answers will read the same way, because the same structure of definition, numbered points, table and conclusion is repeated for every question in the file.
Definition, characteristics and IUBMB classification of enzymes
Question: Define the term 'enzyme'. Write the general characteristics of an enzyme. Describe the IUBMB classification of enzymes with examples.
Answer. Enzymes are highly specialised proteins that catalyse biochemical transformations with very high specificity. The word comes from Greek, en meaning in and zyme meaning leaven, and was coined in 1878 by Friedrich Wilhelm KΓΌhne. Nearly all enzymes are proteins, ribozymes being the exception.
Four characteristics carry the marks. Very high rate, since an enzyme catalysed reaction runs 106 to 1012 times faster than the uncatalysed one. Specificity towards both substrate and product. Mild conditions, below 100°C and near neutral pH. A control mechanism through covalent modification and allosteric regulation. Enzymes do not shift the point of chemical equilibrium.
In 1964 the International Union of Biochemistry and Molecular Biology set up an Enzyme Commission which sorted enzymes into six classes by the reaction catalysed, each enzyme receiving a four digit EC number. Hexokinase, for instance, is 2.7.1.1.
| Class | Reaction catalysed | Example |
|---|---|---|
| Oxidoreductases | Oxidation or reduction | Malate dehydrogenase, catalase |
| Transferases | Transfer of a group between two molecules | Hexokinase |
| Hydrolases | Hydrolysis, group transfer to water | Trypsin, lysozyme |
| Lyases | Addition or removal of a group | Pyruvate decarboxylase |
| Isomerases | Isomerisation, intramolecular transfer | Triose phosphate isomerase |
| Ligases | Ligation of two substrates | Aminoacyl tRNA synthetase |
Conclusion. Enzymes are protein biocatalysts that act fast and only on their own substrate, and the EC system gives every one of them a single clear four digit number.
Michaelis-Menten equation, Lineweaver-Burk plot, Km and Vmax
Question: Write the Michaelis-Menten equation and explain the meaning of each term. Derive the Lineweaver-Burk equation from it, explain the significance of Km and Vmax, and define turnover number.
Answer. The Michaelis-Menten equation links initial reaction velocity with substrate concentration. For the scheme E + S ⇌ ES → E + P the equation is vo = Vmax [So] / (Km + [So]). Here vo is the initial velocity, Vmax the maximum velocity when all enzyme is bound, [So] the initial substrate concentration and Km the Michaelis constant, equal to (k−1 + k2) / k1.
Michaelis and Menten assumed rapid equilibrium. Briggs and Haldane in 1925 introduced the steady state idea in which [ES] stays constant, and the equation holds with Ks replaced by Km. A plot of vo against [S] is hyperbolic, which makes Vmax and Km hard to read off accurately.
Lineweaver and Burk solved that in 1934 by inverting the equation into a double reciprocal plot. Inverting gives 1/vo = (Km + [So]) / Vmax[So], and splitting the terms gives 1/vo = 1/Vmax + Km/Vmax[So]. This is the straight line form y = mx + c, with slope Km/Vmax, y intercept 1/Vmax and x intercept −1/Km.
A small Km means very high affinity, so Km is also called the affinity constant. A large Km means the enzyme needs a lot of substrate to saturate, so affinity is low. Turnover number kcat equals Vmax divided by total enzyme concentration and has units of per second. Carbonic anhydrase turns over 400,000 to 600,000 times a second.
Conclusion. The equation ties reaction speed to substrate concentration and Km shows how tightly the enzyme holds its substrate, while the Lineweaver-Burk plot straightens the same curve so both constants can be read from the intercepts.
Reversible and irreversible enzyme inhibition
Question: Differentiate between reversible and irreversible enzyme inhibition. Describe competitive, uncompetitive and non-competitive inhibition with suitable examples.
Answer. Molecules that bind an enzyme and lower its activity are inhibitors, and inhibition falls into two families. Reversible inhibitors bind non-covalently through several weak bonds, activity returns once the inhibitor is removed, and dialysis or dilution is enough to remove them. Irreversible inhibitors make or break covalent bonds with amino acid residues, and the activity is gone for good.
In competitive inhibition the substrate and inhibitor fight for the same site. The inhibitor usually resembles the substrate, so more substrate can overcome it. Km rises and Vmax stays the same. Malonate competitively inhibits succinate dehydrogenase, and allopurinol inhibits xanthine oxidase, which is why it is used in gout.
Uncompetitive inhibitors do not touch free enzyme at all. They bind the enzyme substrate complex and form a dead end complex, so extra substrate does not help. Both Km and Vmax change while the Lineweaver-Burk slope stays put. Hydrazine on aryl sulphatase is the book example.
Non-competitive inhibitors attach away from the active site and will bind free enzyme or the enzyme substrate complex. Km is unchanged and Vmax drops. Chymotrypsin inhibited by H+ is the example given. Suicide inhibitors sit in the irreversible group, staying quiet until catalysis makes them reactive, as penicillin does to transpeptidase.
Conclusion. Hold on to the pattern. Competitive changes Km, non-competitive changes Vmax, uncompetitive changes both. Reversible inhibition washes out, irreversible does not, which is exactly why so many drugs are built that way.
Multienzyme complexes and LDH isoenzymes
Question: What are multienzyme complexes? Give their properties and advantages and describe the fatty acyl synthase complex. Explain isoenzymes and discuss the LDH forms and their clinical significance.
Answer. A multienzyme complex is a stable assembly of more than one enzyme, generally handling steps that follow one another. Pyruvate dehydrogenase with three enzymes and fatty acyl CoA synthase with six are the standard examples. Four advantages carry marks: reduced transit time, reduced transient time, channelling of intermediates so flux is not lost, and coordinate activation of the whole protein together.
Fatty acids are built from acetyl CoA and malonyl CoA, and chain extension needs transacylations, two reductions, a dehydration and a condensation, which is six catalytic activities. Type I is an aggregated multienzyme protein found in animal and avian tissues, while type II in archaea and bacteria uses separate monofunctional enzymes.
Isoenzymes, in the words of Markert and Møller, are multiple enzyme forms within a single species. Only forms arising from a genetically determined difference in primary structure qualify, and they are numbered by electrophoretic mobility with number 1 the fastest.
LDH separates into five forms, each of molecular weight 135,000, built at random from subunits A and B as B4, AB3, A2B2, A3B and A4. Normal serum runs LDH-2 > LDH-1 > LDH-3 > LDH-4 > LDH-5. Myocardial infarction lifts LDH-1 and LDH-2, while hepatitis lifts LDH-5.
Conclusion. Multienzyme complexes save time and stop intermediates leaking away, and because the five LDH forms differ only in subunit ratio, that ratio in serum points to the damaged organ.
Immobilised enzymes, properties, types and methods
Question: Define immobilised enzymes and describe their properties. Describe the different types and methods of enzyme immobilisation.
Answer. An enzyme physically attached to an inert insoluble support medium is an immobilised enzyme, and the point of doing it is commercial, because the enzyme can then be used again. Four properties are asked for. Stability generally improves as autodigestion drops, and inorganic carriers hold up better than organic polymers. Tertiary structure is affected and crowding causes steric hindrance.
The microenvironment of the support matters too, since charged amino acids and matrix groups can cause desorption. The pH optimum shifts down when the carrier is polyanionic and up when it is polycationic.
Methods split into two groups. Entrapment covers gel, fibre and microencapsulation. Binding covers carrier binding, which is covalent, ionic, chelation or physical adsorption, plus cross linking. Gel entrapment is cheap and quick but gels leak. Fibre entrapment uses cellulose acetate in methylene chloride. Microcapsules run 1 to 100 µm and give more surface area.
Covalent binding is strong and stops leakage but can cost activity, using diazotisation, amide bond formation, alkylation or Schiff's base formation. Ionic binding through DEAE and CM keeps activity high. Chelation uses titanium (III) and zirconium (IV). Cross linking with glutaraldehyde gives cross linked enzyme aggregates.
Conclusion. Immobilisation pins the enzyme to a support so it can be reused. Entrapment cages the enzyme and binding fastens it, and each method trades a little stability against a little activity.

One point worth stating plainly. This file answers the BBCCT-107 theory paper only. The laboratory work of the same paired course sits under BBCCL-108 and is assessed separately, so the practical file for that lab course is a different deliverable and is not part of this PDF.
The file also carries three short guidance pages after the answers. One explains the exam pattern across sessions, one lists what is safe to skip, and one sets out what examiners reward. Students who read those three pages before starting their revision tend to plan their week far better than those who go straight to the answers.

Block titles and unit titles above follow IGNOU's own listing on eGyanKosh, the university's official digital repository, so the mapping matches the book you already have. Where you want the full unit text alongside these answers, our BBCCT 107 Study Material page carries the block wise reading order.
How the BBCCT 107 Important Questions Were Shortlisted
The 16 questions were chosen after reading four IGNOU question papers of BBCCT-107 in full, December 2023, December 2024, June 2025 and December 2025, and marking every topic that repeated along with every full unit that had gone quiet. Both groups matter, because a topic that has skipped two sessions is often the one that returns next.
The working method was simple and repeatable. First, each question in each paper was tagged to its block and unit. Second, topics were counted across the four sessions and sorted into High, Medium and Low. Third, the units with no recent question were pulled up as gap candidates. Only then were the answers written, straight from the IGNOU book rather than from any outside source.
That last part is deliberate. IGNOU examiners mark against the university's own book, and an outside definition can read as wrong even when it is scientifically fine. So author names and years appear exactly where the book gives them, Fisher, Koshland, Michaelis and Menten, Lineweaver and Burk, Markert, Page and Jencks, Harden and Young. Where the book gives no name, none was invented.
If you want to run the same check yourself, start from the actual papers. Our IGNOU Previous Year Question Paper section holds the session wise papers you would need to repeat this exercise for BBCCT-107 or for any other course in your programme.
Repeat Topic Frequency in BBCCT 107 Enzymes Question Papers
Four Enzymes topics appeared in every one of the four sessions studied, and eleven more appeared in at least two, which is what makes a 16 question shortlist realistic for a 70 mark paper. The extract below shows the pattern for the topics that decide most of the paper.
| Enzymes topic | Dec 2023 | Dec 2024 | June 2025 | Dec 2025 | Times | Priority |
|---|---|---|---|---|---|---|
| Sequential and ping-pong bi-bi reactions | Yes | Yes | Yes | Yes | 4 | High |
| Immobilised enzymes and methods | Yes | Yes | Yes | Yes | 4 | High |
| Michaelis-Menten equation | Yes | No | Yes | Yes | 3 | High |
| Coenzymes NAD+, PLP, biotin, lipoic acid | Yes | No | Yes | Yes | 3 | High |
| Isoenzymes and LDH forms | No | Yes | Yes | Yes | 3 | High |
| Competitive and uncompetitive inhibition | No | Yes | Yes | Yes | 3 | High |
| Effect of metal ions on enzyme activity | Yes | No | No | Yes | 2 | High |
| Mechanism of lysozyme action | No | Yes | No | Yes | 2 | High |
| Enzymes in medical diagnosis | No | No | Yes | Yes | 2 | High |
| Lock and key with induced fit models | Yes | No | No | Yes | 2 | High |
| Transition state analogues | No | No | No | Yes | 1 | Medium |
| Zymogens and chymotrypsinogen activation | No | Yes | No | No | 1 | Medium |
| Enzyme electrodes and biosensors | No | No | No | Yes | 1 | Medium |
| Feedback regulation and its types | Yes | No | No | No | 1 | High |
Notice the last row. Feedback regulation was asked once, in December 2023, and has stayed away for three sessions since. It is still tagged High rather than Low, because a whole unit that has gone quiet for three sessions is overdue rather than safe. That reasoning is applied consistently across the full frequency chart inside the file.
BBCCT 107 Enzymes Exam Pattern and Marking Scheme
The BBCCT-107 Term End Examination runs 3 hours for 70 marks, is printed in both English and Hindi, and may be answered in either language. The internal side carries the remaining 30 marks through one tutor marked assignment worth 100, of which 35 per cent is the pass mark.
The shape of the theory paper has shifted between sessions, which is why the file prepares you for two formats rather than one. In December 2023 Question 1 was compulsory and you answered any five from Q2 to Q8. In December 2024 and June 2025 you attempted any five questions of 14 marks each. In December 2025 the paper moved to any seven questions of 10 marks each.
Practically, that means a 14 mark question is normally 7 + 7 in two parts and a 10 mark question is normally 5 + 5, while short notes appear as 2 × 7. The word targets in the file follow that split, roughly 350 words at 14 marks, 250 at 10 marks and 150 for a 5 mark part. The papers themselves state no word limit, so treat these as marks based guides.
December 2025 also carried an instruction to draw diagrams or illustrations wherever required, so keep the Michaelis-Menten curve, the Lineweaver-Burk plot, the temperature and pH curves, the catalytic triad and the Cleland plots ready. Students preparing several papers of the same degree usually pick up the wider BSCBCH guess Paper set for the remaining core courses.
Who Should Use This BBCCT 107 Solved Guess Paper for Enzymes
This BBCCT 107 Solved Guess Paper suits any learner sitting the Enzymes theory paper who has limited time and wants a defined, finishable question set rather than an open ended syllabus. It is not a substitute for the book if you have three months in hand, and we would rather say so than oversell it.
It fits best in four situations. You are two to four weeks from the exam and need to decide what to revise first. You are a repeater who has already read the units once and needs answers in exam shape. You come from a chemistry or life sciences background and find the book's phrasing heavy. Or you simply want a written model of what a full marks answer looks like before you attempt your own.
It fits least well if you have not opened the study material at all. The answers assume you can follow a Lineweaver-Burk derivation and recognise a catalytic triad. Students enrolled in the Bachelor of Science (Honours) Biochemistry programme normally read the relevant unit once, then use these answers to compress it into something writable in the hall.
Every answer has been checked by our academic team before release. Prateek Talwar prepared the question shortlist from the session papers, and Sheetal Kirola, who holds an M.Ed. and heads academics at Unnati Educations, reviewed the answers for accuracy against the IGNOU book and for language that a distance learner can actually retain.
How to Get the Complete BBCCT 107 Enzymes Guess Paper on WhatsApp
Send an enquiry on WhatsApp 9899436384 with your course code, BBCCT-107, and the session you are appearing for, and our team will share the availability, the price and the full PDF once your order is confirmed. The 11 answers not sampled on this page are supplied in that file, together with the three guidance pages.
Three details make the reply faster. Mention BBCCT-107 by code rather than by subject name, since several biochemistry courses have similar titles. Tell us whether you want it for the December 2026 session. And say if you need any other course of the same programme, so the team can quote everything in one message instead of four.
The file is delivered as a print ready PDF, so you can either read it on your phone or take a printout and write practice answers beside it. We would suggest the second. Writing three of these 16 answers in full, on paper, with a clock running, is worth more than reading all 16 twice.
Frequently Asked Questions About the BBCCT 107 Enzymes Guess Paper
How many questions does the BBCCT 107 Solved Guess Paper contain?
The BBCCT 107 file contains 16 questions, each with a complete written answer. Five of those answers are shown as samples on this page, so 11 remain in the file you receive after enquiry. The 16 questions span all four blocks and all twelve units of the Enzymes syllabus, and each one carries its block reference, marks split, last appearance and revision priority alongside the answer itself.
Which question papers were studied to build the BBCCT 107 guess paper?
Four IGNOU Term End papers of BBCCT-107 were read in full, from December 2023, December 2024, June 2025 and December 2025. Every question in each paper was tagged to its block and unit, then topics were counted across the four sessions. Topics repeating three or four times were marked High priority, and units that had gone unasked for several sessions were pulled up as likely gap questions.
Is the BBCCT 107 Enzymes guess paper written from the official IGNOU book?
Yes. Every definition, author name, year and list count is taken from the IGNOU BBCCT-107 study material, and only the explanation under each point has been rewritten in simpler English. No outside textbook was used. This matters because IGNOU examiners mark against the university's own book, so an outside definition can cost marks even when it is scientifically correct.
Does the BBCCT 107 guess paper cover the practical or laboratory component?
No. This file answers the BBCCT-107 theory paper only, which is the 70 mark Term End Examination. The laboratory work of the paired course is assessed separately under BBCCL-108 and needs a different practical file. If you need help with that lab record as well, mention it in your WhatsApp enquiry and the team will tell you what is available.
What is the exam pattern for the BBCCT 107 Enzymes Term End Examination?
The paper runs three hours for 70 marks and is printed in both English and Hindi. The pattern has shifted between sessions. December 2024 and June 2025 asked for any five questions of 14 marks each, while December 2025 asked for any seven of 10 marks each. A 14 mark question is usually 7 + 7 and a 10 mark question usually 5 + 5, so prepare for both shapes.
Can I pass BBCCT 107 by reading only this Enzymes guess paper?
It gives you a strong, finishable question set, but we will be straight with you. The file works best when you have already read the units once, because the answers assume you can follow a derivation and recognise a catalytic triad. Used alongside the study material in your final two to four weeks, it saves a great deal of time and shows you the shape an examiner rewards.
How is the BBCCT 107 Solved Guess Paper delivered after I enquire?
Send a message on WhatsApp 9899436384 mentioning the course code BBCCT-107 and the session you are appearing for. The team replies with availability and price, and the print ready PDF is shared once your order is confirmed. Enquiries received during working hours are usually answered the same day. Nothing is sent automatically, so please message us rather than waiting.
Which session is the BBCCT 107 Enzymes guess paper meant for?
It was prepared for the 2026 Term End Examination cycle of BBCCT-107, with the December 2026 session as the current live target. Because the shortlist is built on topics that repeat across sessions rather than on one paper, it stays useful for the next cycle too. Mention your session in the enquiry and we will confirm whether an updated edition is ready.
