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.
