During alcoholic fermentation by yeast two molecules of glucose produce

Options

(a) 2 molecules of ethanol +2 molecules of CO₂
(b) 4 molecules of ethanol +4 molecules of CO₂
(c) 6 molecules of ethanol +6 molecules of CO₂
(d) 3 molecules of ethanol +3 molecules of CO₂

Correct Answer:

4 molecules of ethanol +4 molecules of CO₂

Explanation:

Alcoholic fermentation is incomplete oxidation of glucose under anaerobic conditions. One molecule of glucose yield 2 molecules of ethyl alcohol and 2 molecules of CO₂. So, 2 molecules of glucose will give 4 molecules of both.
