Compared with the 36 to 38 ATP of aerobic respiration, anaerobic respiration in a human muscle cell yields
- A. no ATP at all
- B. 4 ATP per glucose
- C. 2 ATP per glucose
- D. 24 ATP per glucose
Explanation
Only glycolysis runs without oxygen, giving a net gain of 2 ATP, while the Krebs cycle and electron transport chain need oxygen to continue. This is why muscles tire quickly when they have to rely on lactate fermentation.
