RGUHS Biochemistry Question Papers (2025-2021)

RGUHS Biochemistry Papers: All Years

Biochemistry is a Phase 1 (1st Year) subject under the NMC CBME curriculum, examined as part of the Phase 1 university assessment alongside Anatomy and Physiology. The five papers below span 2021 to 2025.

Note on marks: The external theory paper carries 80 marks. Internal Assessment (IA) contributes an additional 20 marks, making the total subject marks 100. The breakdown of long essay and short note questions within the external paper should be confirmed from the official RGUHS examination notification for your year.

RGUHS Biochemistry Exam Pattern

RGUHS Biochemistry theory examinations follow the NMC CBME format for Phase 1 subjects.

Question format under NMC CBME: Long essay questions test higher-order understanding — they require a complete, structured answer covering definition, mechanism, diagram (where applicable), and clinical relevance. Short notes test specific facts, pathways, and applied concepts within a constrained answer. Biochemistry papers under the CBME framework increasingly frame questions around clinical application: a metabolism pathway question may be anchored to a patient with an enzyme deficiency rather than asked in pure isolation.

Commonly Tested Topics in RGUHS Biochemistry (2021-2025)

The following areas recur consistently across RGUHS Biochemistry papers from 2021 to 2025. This analysis is based on available RGUHS paper archives and NMC CBME Phase 1 curriculum weighting. Exam prediction is not guaranteed — use this as a revision priority guide, not an attempt to spot questions.

Topics listed as High priority appear with the greatest frequency and consistency across the five-year archive. Topics listed as Medium priority appear regularly but with slightly less predictable distribution across years.

Study Tips for RGUHS Biochemistry Exams

• Learn the Krebs cycle from memory before the exam, not just for recognition. The Krebs cycle diagram is the single most examined biochemistry diagram across RGUHS papers and across most other universities. Practise drawing it from memory — substrates, enzymes, products, and the points at which CO₂ and reduced coenzymes are generated — so you can reproduce it under exam conditions in under five minutes. Use the Krebs cycle diagram on GeckoMed as the drawing reference.
• Structure vitamin answers using a five-point framework. Vitamins appear as both long notes and short notes in RGUHS Biochemistry papers. A reliable five-point structure for every vitamin short note: chemical name, source (dietary), biochemical function, deficiency disease and its features, toxicity if fat-soluble. Preparing vitamins this way gives you a complete answer for any vitamin regardless of which one the question targets.
• Connect metabolism pathways to clinical deficiency states. RGUHS Biochemistry papers under the NMC CBME framework increasingly frame questions around clinical presentations — a patient with phenylketonuria, a neonate with jaundice, a patient with pellagra. Cross-referencing your pathway knowledge with the clinical features of enzyme deficiencies and vitamin deficiencies prepares you for both the classically worded question and the case-framed variant.
• Prepare practical and viva as a separate track from theory. Biochemistry practical examinations cover urine analysis (detecting abnormal constituents such as glucose, proteins, bile pigments, and ketone bodies), basic biochemical tests, and applied interpretation questions. The biochemistry practical viva questions on GeckoMed cover the most common viva topics from a practical session perspective.
• Use cross-year frequency to prioritise topics, not just the most recent paper. With five years of RGUHS Biochemistry papers available, the strongest revision signal comes from topics that appear in multiple years, not just in 2025. Start with the 2025 paper, identify topics, then verify which ones also appeared in 2023, 2022, and 2021. Topics that recur across three or more years are your highest-priority revision targets.
• Do not skip Molecular Biology topics. DNA replication, transcription, and translation are sometimes treated as secondary by students who find metabolism pathways more intuitive. In RGUHS papers, molecular biology topics appear consistently as long essay questions. A complete answer for DNA replication should cover the enzymes involved (helicase, primase, DNA polymerase, ligase), the leading and lagging strand mechanism, and Okazaki fragments.
