NEET-PG & INICET Biochemistry — Complete Preparation Guide 2026

Quick Answer

Biochemistry carries 6–8% weightage in NEET-PG & INICET — approximately 24–32 questions out of 300. The highest-yield topics are Enzyme kinetics — Michaelis-Menten, competitive vs. non-competitive inhibition, Glycolysis, TCA cycle, gluconeogenesis — key enzymes and regulation, Fatty acid synthesis and beta-oxidation — regulation and energetics, and biochemistry questions in neet-pg & inicet focus heavily on clinical correlations of metabolic pathways — enzyme deficiencies, vitamin deficiency presentations, and porphyrias.

High-Yield Biochemistry Topics for NEET-PG & INICET

These are the topics that have appeared most frequently in NEET-PG & INICET papers across the last 10 sessions. Cover them first — together they account for roughly 70% of the Biochemistry marks distribution.

  1. Enzyme kinetics — Michaelis-Menten, competitive vs. non-competitive inhibition
  2. Glycolysis, TCA cycle, gluconeogenesis — key enzymes and regulation
  3. Fatty acid synthesis and beta-oxidation — regulation and energetics
  4. Protein synthesis — translation, post-translational modifications
  5. Vitamins — coenzyme functions, deficiency diseases
  6. Porphyrin metabolism — haem synthesis, porphyrias, jaundice types
  7. DNA repair mechanisms and mutations
  8. Inborn errors of metabolism — PKU, alkaptonuria, Gaucher, Tay-Sachs

How Biochemistry Is Tested in NEET-PG & INICET

Biochemistry questions in NEET-PG & INICET focus heavily on clinical correlations of metabolic pathways — enzyme deficiencies, vitamin deficiency presentations, and porphyrias. Direct questions on metabolic intermediates are less common than application-based scenarios.

Study Tip — How to Prepare Biochemistry Efficiently

Link every metabolic pathway to its clinical disease. For example: pyruvate dehydrogenase deficiency → Leigh disease → lactic acidosis. Build a disease-enzyme-pathway map rather than memorizing pathways in isolation.

Common Mistake to Avoid

Trying to memorize every intermediate in every pathway. NEET-PG & INICET consistently tests the regulatory enzymes and the clinical consequence of their deficiency — not the full sequence of intermediates.
