Which of the following statement regarding pyruvate during aerobic respiration is incorrect?
1 Itis formed by the glycolytic catabolism of carbohydrates in the mitochondrial matrix.
2 It enters mitochondrial matrix & undergoes oxidative decarboxylation.
3 The conversion of pyruvic acid to acetyl CoAis catalysed by pyruvic dehydrogenase.
4 Two molecules of NADHare produced from the metabolism of two molecules of pyruvic acid.
Explanation:
(a) Pyruvate, is formed by the glycolytic catabolism of carbohydrates in the cytosol, after that it enters mitochondrial matrix and undergoes oxidative decarboxylation by a complex set of reactions catalyzed by pyruvic dehydrogenase.

In respiration, largest amount of energy is produced in:
1 anaerobic respiration
2 Krebs' cycle
3 glycolysis
4 none of the above
Explanation:
(b) In Krebs' cycle, number of ATP molecules are produced in large amount i.e. 24. Therefore it generates large amount of energy.
