What happens to glucose in aerobic respiration that does not happen in fermentation?
Options
- AIt is converted to pyruvic acid
- BIt is completely degraded to CO₂ and H₂O
- CIt produces only two ATP molecules
- DIt undergoes partial breakdown
Correct answer
B. It is completely degraded to CO₂ and H₂O
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
