Question

In alcoholic fermentation, two molecules of glucose produce ethanol and CO${}_2$ respectively

• A. 2 + 2
• B. 3 + 3
• C. 4 + 4
• D. 6 + 6

Answer 1

Answer: (C)

4 + 4

Alcoholic respiration is done by the yeast in which two molecules of ATP, carbon dioxide and alcohol is released and the process takes place in the absence of oxygen.

$C_6{H}_{12}{O}_6+2ADP\to Pi2C_2{H}_{5}OH+C{O}_2+2ATP$

If 2 ATP and $C_2$ is released by molecule. So two glucose will release 4 ATP and CO_2$.

So the correct option is '4 + 4'.
