Question

For the same amount of glucose, aerobic respiration liberates ___ times more energy than anaerobic respiration.

• A. Same
• B. 19
• C. 38
• D. 2

Answer 1

The correct option is B

19

In aerobic respiration 38 molecules of ATP are released for each glucose molecule. In anaerobic respiration, just 2 molecules of ATP are released per glucose molecule. So, aerobic respiration generates 19 times more energy than anaerobic respiration for same amount of glucose.
