Expected Weightage
The Common University Entrance Test (CUET) for Biochemistry of Metabolism has shown some consistent trends in its marking pattern and chapter-wise weightage over the past three years (2021-2023, assuming CUET-PG data is considered). Below is a structured analysis based on available trends:
1. Overall Marking Pattern (CUET-PG Biochemistry)
- Total Marks: Typically 100 marks (MCQ-based).
- Number of Questions: ~50-75 (varies yearly).
- Negative Marking: Usually -1 for wrong answers (if applicable, varies by university).
- Difficulty Level: Moderate to high, with emphasis on conceptual clarity and application.
2. Chapter-wise Weightage (Last 3 Years)
Based on previous years’ trends, the following chapters have been frequently tested with approximate weightage:
| Chapter/Topic | Weightage (Approx. %) | Key Subtopics |
|---|---|---|
| Carbohydrate Metabolism | 20-25% | Glycolysis, TCA cycle, Gluconeogenesis, Glycogen metabolism, PPP |
| Lipid Metabolism | 15-20% | Fatty acid oxidation, Ketogenesis, Cholesterol metabolism, Lipoproteins |
| Amino Acid Nitrogen Metabolism | 15-20% | Urea cycle, Transamination, Amino acid catabolism, Nucleotide metabolism |
| Bioenergetics Oxidative Phosphorylation | 10-15% | ETC, ATP synthesis, Chemiosmotic theory, Uncouplers |
| Enzyme Kinetics Regulation | 10-12% | Michaelis-Menten, Allosteric regulation, Inhibitors |
| Hormonal Regulation of Metabolism | 8-10% | Insulin, Glucagon, Adrenaline, Thyroid hormones |
| Integration of Metabolism | 5-8% | Fed vs. Fasted state, Metabolic disorders |
| Vitamins Coenzymes | 5-7% | B-complex vitamins, Coenzyme functions |
| Specialized Metabolism (Heme, etc.) | 3-5% | Porphyrin synthesis, Bilirubin metabolism |
3. Trends Observed (2021-2023)
- High Weightage:
- Carbohydrate Lipid Metabolism (consistently 40-45% combined).
- Amino Acid Metabolism (urea cycle is frequently tested).
- Moderate Weightage:
- Bioenergetics Enzymes (often application-based).
- Low but Consistent:
- Hormonal Regulation Vitamins (mostly factual).
- Emerging Topics:
- Metabolic disorders (e.g., Diabetes, PKU) are gaining importance.
4. Preparation Tips
- Focus heavily on Glycolysis, TCA cycle, Fatty acid metabolism, and Urea cycle (highly repeated).
- Practice numerical problems on enzyme kinetics and bioenergetics.
- Revise clinical correlations (e.g., G6PD deficiency, Ketosis).
- Previous years’ CUET-PG papers show repetition of concepts , so solving them is crucial.
