Question

Pyruvate undergoes oxidative decarboxylation to produce

• A. 2-PGA.
• B. $\alpha$ -Ketone.
• C. Succinyl Co-A.
• D. Acetyl Co-A.

Answer 1

The correct option is D Acetyl Co-A.

Pyruvate is formed as the product of glycolysis. It is converted into acetyl coenzyme A by the process of oxidative decarboxylation, which is catalysed by the pyruvate dehydrogenase enzyme. The formed acetyl coenzyme A is used in the citric acid cycle as a fuel. So, the correct option is D.
