Which two enzymes catalyse alcoholic fermentation?
ADecarboxylase and dehydrogenase
BDecarboxylase and dehydratase
CDecarbonase and dehydrogenase
DDecarbonase and dehydratase
Answer & Solution
Correct answer: A. Decarboxylase and dehydrogenase
1. One enzyme removes carbon dioxide from pyruvic acid.
2. The other reduces the product to alcohol.
3. Pyruvic acid decarboxylase and alcohol dehydrogenase catalyse these reactions.
4. So the answer is decarboxylase and dehydrogenase.
