Questions
Oxidative decarboxylation is observed in which step of aerobic respiration?
a
Conversion of oxaloacetic acid to citric acid
b
Conversion of succinic acid to fumaric acid
c
Conversion of phosphoenolpyruvate to pyruvic acid
d
Conversion of pyruvic acid to acetyl CoA
detailed solution
Correct option is D
Pyruvate, which is formed by the glycolytic catabolism of carbohydrates in the cytosol, after it enters mitochondrial matrix undergoes oxidative decarboxylation by a complex set of reactions catalysed by pyruvic dehydrogenase. The reactions catalysed by pyruvic dehydrogenase require the participation of several coenzymes, including NAD+ and Coenzyme A.Pyruvic acid+CoA+NAD+→Pyruvate dehydrogenaseMg2Acetyl CoA+CO2+NADH+H+Talk to our academic expert!
