Biochemistry for NEET PG

Biochemistry splits into metabolism, molecular biology and clinical correlations. The highest-return habit is linking each enzyme deficiency to the disease, its inheritance and its signature finding.

What Biochemistry covers

  • Biomolecules and enzymes
  • Carbohydrate metabolism
  • Lipid metabolism
  • Amino acid metabolism
  • Nucleotide metabolism
  • Vitamins and minerals
  • Molecular biology and genetics
  • Clinical biochemistry

How to study it

  1. 1

    Build one table of enzyme deficiency, disease, inheritance and key finding, then revise it by spaced recall.

  2. 2

    Know the regulated, rate-limiting step in each pathway and what activates or inhibits it.

  3. 3

    Revise vitamins as a clinical set: the deficiency picture, the lab marker, the cofactor role.

Where students slip

  • Learning pathways as diagrams with no sense of which step is controlled.
  • Mixing up similar-sounding inborn errors.

Four quick-revision cards

  • Rate-limiting enzyme of glycolysis?

    Phosphofructokinase-1.

  • Enzyme deficient in Lesch–Nyhan syndrome, and its inheritance?

    HGPRT; X-linked recessive. Self-mutilation, dystonia, high uric acid.

  • How do you tell B12 from folate deficiency biochemically?

    Methylmalonic acid is raised in B12 deficiency only; homocysteine is raised in both.

  • Rate-limiting enzyme of cholesterol synthesis and its drug?

    HMG-CoA reductase; inhibited by statins.

Common questions

What is the fastest way to revise biochemistry?

Tables of enzyme deficiencies and vitamin syndromes, revised with flashcards.

Do I need to memorise full pathways?

Know the key intermediates, the rate-limiting enzyme and the disease that results when a step fails.
