Match List-I with List-II

Column I

  • A. Oxidative decarboxylation
  • B. Glycolysis
  • C. Oxidative phosphorylation
  • D. Tricarboxylic acid cycle

Column II

  • I. Citrate synthase
  • II. Pyruvate
  • III. Electron transport system
  • IV. EMP pathway

Correct answer: A → II, B → IV, C → III, D → I

Solution

Pyruvate undergoes oxidative decarboxylation; glycolysis is the EMP pathway; the TCA cycle uses citrate synthase.

Pyruvate when enters into mitochondrial matrix, it undergoes oxidative decarboxylation by a complex set of reactions catalysed by pyruvic dehydrogenase. Glycolysis is often referred to as the EMP pathway. Oxidative phosphorylation is a process embedded in the inner membrane of mitochondria (called electron transport chain and ATP synthase). The reaction in TCA cycle is catalysed by the enzyme citrate synthase.
