NTRUHS Biochemistry Question Papers (2025 to 2021)

NTRUHS Biochemistry Papers: Year-Wise Collection

Biochemistry is a Phase 1 / 1st Year MBBS subject at NTRUHS. The university theory examination covers metabolism, molecular biology, clinical biochemistry, enzymology, nutrition, and applied biochemistry topics under the NMC CBME framework. Year-wise papers are available below. Additional years will be added as they become available.

NTRUHS Biochemistry Exam Pattern

NTRUHS conducts Phase 1 MBBS examinations under the National Medical Commission (NMC) Competency-Based Medical Education (CBME) framework. The table below reflects the standard structure for the NTRUHS Biochemistry theory examination. Confirm specific marking and internal assessment norms from the official NTRUHS exam notification for your batch.

Mark allocation: The NTRUHS Biochemistry theory paper follows the NMC CBME format with Long Essay Questions carrying 10 marks each and Short Answer Questions carrying five marks each. Verify the exact question count for the current year from the official NTRUHS exam notification.

Practical and viva: The Biochemistry practical examination at NTRUHS covers qualitative and quantitative analysis techniques: urine analysis for glucose, proteins, ketone bodies, and bile salts; blood glucose estimation; and other clinical chemistry experiments. Viva questions in practicals focus on the biochemical basis of each experiment and clinical applications. See Biochemistry Practical Viva Questions and Biochemistry Viva Questions and Answers for dedicated viva preparation.

How to Study NTRUHS Biochemistry With PYQs

Biochemistry is one of the subjects 1st year MBBS students consistently find abstract. The key is to anchor each topic to a metabolic pathway or a clinical application -- not to memorise reactions in isolation. These tips are specific to how the NTRUHS theory paper is framed.

• Work with pathway diagrams from the start. Glycolysis, the Krebs cycle, beta-oxidation, the urea cycle -- these are best learnt as drawn pathways, not as text lists. Reproduce each pathway from memory daily during revision, adding enzymes and regulatory points. A pathway you can draw is a pathway you can explain in an exam.
• Supplement the two available NTRUHS papers with papers from other universities. Because fewer NTRUHS Biochemistry year pages are currently in the collection compared to subjects like Anatomy and Physiology, use the TNMGRMU, RGUHS, and KNRUHS Biochemistry archives for volume practice. All follow the NMC CBME pattern.
• Clinical applications are the examiner's favourite frame. Gout, phenylketonuria, maple syrup urine disease, alkaptonuria, ketoacidosis in diabetes, jaundice biochemistry -- each maps to a metabolic pathway. For every pathway topic you revise, prepare one clinical application short note. These appear both as standalone short answers and as the applied section of long essay questions.
• Vitamins and minerals are reliable short answer marks. A vitamin question appears in almost every Biochemistry theory paper across Indian medical universities: function, deficiency disease, and sometimes the biochemical mechanism of deficiency. Prepare a compact table: fat-soluble vitamins, water-soluble vitamins, key roles, and deficiency syndromes.
• Enzyme questions reward clear definitions. Enzyme kinetics (Michaelis-Menten), inhibition types, and isoenzyme clinical utility (LDH, CPK, alkaline phosphatase) are regularly asked. Know the graphs for competitive and non-competitive inhibition and what each parameter shift means clinically.
• Link the practical to the theory paper. Understanding the biochemical principle behind urine glucose detection (Benedict's test) or urine ketone testing directly reinforces the carbohydrate and lipid metabolism topics that appear in theory. Practicals and theory are not separate revision tasks in Biochemistry.
• Molecular biology: focus on applied concepts, not exhaustive detail. At the 1st year MBBS level, DNA replication, transcription, and translation questions ask for mechanisms and clinical relevance (e.g., mechanism of antibiotic action, gene mutations, oncogenes), not doctoral-level molecular detail. Revise these topics to the level they appear in past papers.
