In the conversion of pyruvate to ethanol, which of the following is(are) produced?
A) acetaldehyde

E) acetaldehyde, carbon dioxide, and NADH

Question

Quizplus · Accepted Answer

In the conversion of pyruvate to ethanol, the enzyme pyruvate decarboxylase first removes a carbon dioxide molecule from pyruvate, producing acetaldehyde as a byproduct. The acetaldehyde is then reduced to ethanol by the enzyme alcohol dehydrogenase. Therefore, the products produced in this conversion are acetaldehyde and carbon dioxide only. NADH is an intermediate in this reaction, but not a final product.
