Pyruvate dehydrogenase is used in converting

Options

  1. Aglucose to pyruvate
  2. Bpyruvate to lactate
  3. Cpyruvate to glucose
  4. Dpyruvate to Acetyl Co-A

Correct answer

D. pyruvate to Acetyl Co-A

Step-by-step solution

At the end of glycolysis, 2 molecules of pyruvic acid are formed in the cytoplasm. The 2 molecules of pyruvic acid enters mitochondria to undergo oxidative decarboxylation to form acetyl fraction (2C) in the presence of enzyme pyruvate dehydrogenase and M g 2 + as co-factor. 2 molecules of acetyl fraction (2C) combine with 2 molecules of coenzyme A to form 2 molecules of acetyl coenzyme A (2C). The two molecules of hydrogen released during this reaction are accepted by 2 molecules of coenzyme N A D + and it is redu
