Question

Quizplus · Accepted Answer

The given reaction series is the pathway of branched-chain amino acid (BCAA) degradation. The major end product of BCAA degradation is acetyl-CoA, which can enter the citric acid cycle to generate ATP. Among the BCAAs, only valine undergoes complete oxidative degradation, leading to the formation of acetyl-CoA. Therefore, E) Val is the best choice as the major end product of the given reaction series.
