Before entering the Krebs cycle, pyruvate undergoes decarboxylation and oxidation. Which coenzyme is required to carry the resulting two-carbon fragment?
Q1. Before entering the Krebs cycle, pyruvate undergoes decarboxylation and oxidation. Which coenzyme is required to carry the resulting two-carbon fragment?
Answer: Coenzyme A
Explanation: Coenzyme A carries the acetyl group to the Krebs cycle; FAD and NAD+ are electron carriers, not group carriers.
