Which one of the following reactions is an example of oxidative decarboxylation?
- A Conversion of succinate to fumarate
- B Conversion of fumarate to malate
- C Conversion of pyruvate to acetyl CoA
- D Conversion of citrate to isocitrate
Answer & Solution
Correct Answer
(C) Conversion of pyruvate to acetyl CoA
Step-by-step Solution
Detailed explanation
(C) Conversion of pyruvate to acetyl CoA,
The conversion of pyruvate to acetyl CoA is an example of oxidative decarboxylation. In this reaction, pyruvate undergoes oxidation and decarboxylation (loss of \(CO _2\)) to form acetyl CoA, along with the reduction of NAD to NADH. This reaction is catalyzed by the enzyme pyruvate dehydrogenase and is a crucial step in cellular respiration.
