What is the net gain of ATP molecules for each molecule of glucose in fermentation?
Options
- A2 molecules of ATP
- B4 molecules of ATP
- C36 molecules of ATP
- D38 molecules of ATP
Correct answer
A. 2 molecules of ATP
Step-by-step solution
• Fermentation accounts for only a partial breakdown of glucose whereas in aerobic respiration it is completely degraded to CO₂ and H₂O. • In fermentation there is a net gain of only two molecules of ATP for each molecule of glucose degraded to pyruvic acid whereas many more molecules of ATP are generated under aerobic conditions. • NADH is oxidized to NAD+ rather slowly in fermentation, however the reaction is very vigorous in case of aerobic respiration
