In Anaerobic respiration only __________ % of the energy present within the chemical bond of glucose is converted into ATP?
Correct answer: B. 2%
- A. 1%
- B. 2%
- C. 3%
- D. 4%
Explanation
Anaerobic respiration captures only about 2% of glucose's stored chemical energy in ATP because glycolysis is the only energy-yielding stage and produces a net 2 ATP per glucose. Students may choose 4% because they double the percentage by counting the two ATP-producing steps without considering the much greater total energy stored in glucose.
