How efficient is the breakdown of one glucose molecule via cellular respiration?
A) 100%
B) 58%
C) 39%
D) 20%
E) less than 10%

Question

Quizplus · Accepted Answer

Cellular respiration breaks down glucose into ATP through a series of chemical reactions. However, not all of the energy released during these reactions is converted into usable ATP. The efficiency of cellular respiration is about 39%, with the remaining energy released as heat. This is due to factors such as the release of energy during the production of ATP, which can be lost as heat, and the inefficiency of the electron transport chain in the production of ATP. Therefore, choice C, 39%, is the best answer.
