Solution
The correct option is B Pyruvic acid decarboxylase and alcohol dehydrogenase
Pyruvic acid decarboxylase and alcohol dehydrogenase enzymes act as catalysts for the conversion of pyruvic acid into acetaldehyde and ethyl alcohol respectively. Pyruvate decarboxylase is the enzyme responsible for the non-oxidative decarboxylation of pyruvate to acetaldehyde and carbon dioxide. The acetaldehyde is often then reduced by alcohol dehydrogenase to make ethanol.
Pyruvic acid dehydrogenase converts pyruvate to acetyl CoA. This increases the influx of acetyl CoA into the TCA cycle. Alcohol decarboxylase catalyzes the decarboxylation.
