Question: which one of the following enzymes is involved with oxidative decarboxylation of pyruvate?
Answer: Energy-generating ions and molecules such as amino acids and carbohydrates enter the Krebs cycle as acetyl coenzyme A and oxidize in the cycle. The pyruvate dehydrogenase complex (PDC) catalyzes the decarboxylation of pyruvate resulting in the synthesis of acetyl-CoA, CO2, and NADH.
