Practice question · Estimate
Aerobic respiration yields about 30 ATP per glucose, while fermentation yields 2. Set how many times more energy the aerobic route extracts.
Estimate on a scale from No advantage (0) to Thirtyfold (30).
Hints
- Divide the aerobic yield by the fermentation yield.
- Compute 30 divided by 2.
Show the answer
15 (answers within ±1.5 count)
Why
Aerobic respiration extracts about times more ATP per glucose. That margin is what pays for the size, activity and complexity of animals, anaerobes simply cannot afford them.
