Biochemistry for NEET PG

~10 questions — metabolism, inborn errors and vitamins recur every year.

📊 ~10 Q · ~40 marks (6% of the paper)

How toppers play this section

Biochemistry is examined as a set of blocked pathways: an enzyme fails, a substrate accumulates, and a recognisable clinical picture follows. Learning it that way turns inborn errors, vitamin deficiencies and metabolic disorders into one method instead of three lists. Molecular biology techniques are the modern addition and are worth a dedicated pass, since they are asked in a factual, quickly-secured form.

Chapters

Built to the NEET PG blueprint — notes, shortcuts, solved PYQ-style examples and practice in every chapter.

1Acid-Base & Electrolyte BalanceAcid-base questions are among the few in NEET PG that can be answered with complete certainty, because they are arithmetic rather than recall. This chapter builds the buffer systems, the four primary disorders with their compensation formulae, the anion gap and delta ratio for detecting mixed disorders, and the electrolyte derangements that accompany them.⏱ 21 min read

2Enzymology & MetabolismMetabolism looks like a memory subject but is really a regulation subject — a handful of rate-limiting enzymes decide which pathways run, and hormones act on those enzymes alone. This chapter builds enzyme kinetics, glucose oxidation, the electron transport chain and fuel switching around those control points.⏱ 22 min read

3Hormones & Signal TransductionSignal transduction reduces to a small number of receptor families, and knowing which family a hormone uses predicts its speed, its second messenger and the drugs that modify it. This chapter builds the G protein-coupled receptors, the enzyme-linked receptors, the intracellular receptors, and the toxins and regulatory mechanisms that act on them.⏱ 21 min read

4Inborn Errors & Lysosomal Storage DiseasesEvery inborn error follows one rule — a blocked enzyme means deficiency downstream and accumulation upstream — and the clinical picture is the sum of those two consequences. This chapter builds the amino acid disorders, the urea cycle, the carbohydrate and glycogen defects, and the lysosomal storage diseases around that single principle.⏱ 22 min read

5Molecular BiologyMolecular biology is tested through its failures and its tools — which repair pathway is broken in a cancer syndrome, which polymerase a toxin inhibits, which ribosomal subunit an antibiotic binds. This chapter builds replication and repair, transcription, translation and laboratory technique around those clinical anchors.⏱ 22 min read

6Vitamins & NutritionA vitamin deficiency syndrome is not a list to memorise but the predictable failure of the reactions that vitamin serves. This chapter builds the fat-soluble vitamins, the B group as cofactors, the megaloblastic pair of folate and B12, and the trace elements and malnutrition syndromes around that principle.⏱ 22 min read
