Question

Formation of acetyl-CoA from pyruvic acid is

• A. oxidative phosphorylation
• B. oxidative isomerisation
• C. oxidative decarboxylation
• D. oxidative carboxylation

Answer 1

The correct option is C oxidative decarboxylation

In carbohydrate metabolism, acetyl CoA is the link between glycolysis and the citric acid cycle. This reaction may be called the oxidative decarboxylation of pyruvic acid to acetyl CoA. This oxidative decarboxylation of pyruvic acid is catalyzed by the enzyme complex - pyruvate dehydrogenase.

So, the correct option is, 'Oxidative Decarboxylation'.
