During fermentation in yeast, alcohol dehydrogenase catalyzes a reaction that breaks down acetaldehyde into ethanol and regenerates

Question:

During fermentation in yeast, alcohol dehydrogenase catalyzes a reaction that breaks down acetaldehyde into ethanol and regenerates NAD1. This is the reverse of the reaction catalyzed by the enzyme in humans and other animals.

alcohol dehydrogenase + NADH + H+ > CH;CH2OH + NAD* CH;CHO ethanol acetaldehyde

a. What is oxidized and reduced in this reaction? Explain.

b. What happens to the ethanol after it is produced?

c. What happens to the NAD1 after it is produced?
