When 100% carbon is oxidized to CO2, the efficiency of such respiration is?
Correct answer: A. 40%
- A. 40%
- B. 60%
- C. 90%
- D. 100%
Explanation
Option A suggests that the efficiency of respiration, when 100% carbon is oxidized to CO2, is 40%. It means that approximately 40% of the energy released during respiration is converted to ATP, while the remaining 60% is lost as heat.

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.
