How much energy is present in the chemical bond of glucose that is converted into ATP by anaerobic respiration?
Correct answer: A. 2%
- A. 2%
- B. 4%
- C. 10%
- D. 36%
Explanation
Option A is the correct option because This is the accurate estimate for energy conserved as ATP in anaerobic respiration. The rest of the energy remains in the end products (like lactate or ethanol) as they are not fully broken down.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
