Conversion of pyruvic acid into ethyl alcohol is facilitated by:

Options

ACarboxylase
BDehydrogenase
CDecarboxylase and dehydrogenase
DPhosphatase

Correct answer

C. Decarboxylase and dehydrogenase

Step-by-step solution

In fermentation, by yeast, the incomplete oxidation of glucose is achieved under anaerobic conditions by sets of reactions where pyruvic acid is converted to CO 2 and ethanol. The enzymes, pyruvic acid decarboxylase and alcohol dehydrogenase catalyse these reactions.
