In the reaction that converts acetaldehyde to ethanol, what role does nicotinamide adenine dinucleotide play?

a. it oxidizes acetaldehyde

b. it reduces acetaldehyde

c. it donates electrons to ethanol

a & c

b & c

Expert Solution

Ans: b. it reduces acetaldehyde

&

c. it donates electrons to ethanol.

Acetaldehyde to ethanol conversion is catalysed by alcohol dehydrogenase. In this reaction acetaldehyde reduces to ethanol and the hydrogen ion is taken up from NADH thus NADH oxidizes to NAD+ . In this process it also donates electrons to ethanol.
