A

Alcohol dehydrogenase Pyruvare decarboxylase

B

Alcohol decarboxylase Pyruvate dehydrogenase

C

Pyruvate decarboxylase Alcohol dehydrogenase

D

Pyruvate dehydroganase Alcohol dehydroganase

Text Solution

Verified by Experts

The correct Answer is:
C
The given reaction represents alcoholic fermentation. In alcoholic fermentation.pyruvate is converted into ethanol in a two step pathway. Ethyl alcohol fermentation is quite common in fungi (e.g., Rhizopus yeast) and bacteria. In yeast) and bacteria. In yeast, pyruvate is decarboxylated to form acetaldehyde which is then reduced by NADH to form ethanol.
