A) evolved and enabled living organisms to utilize energy stored in glucose.
B) occurs only in animal cells because plants carry on photosynthesis.
C) utilizes fat as its primary energy source.
D) occurs at the same rate throughout all cells of the body.
E) is the only cellular mechanism that yields ATP.

Question

Quizplus · Accepted Answer

Aerobic respiration is the process by which living organisms break down glucose, releasing energy in the form of ATP. It evolved as a way for organisms to utilize the energy stored in glucose. It occurs in both plant and animal cells, not just animal cells. While fat can be a source of energy in aerobic respiration, glucose is the primary energy source. Aerobic respiration occurs at different rates in different cells, depending on the energy needs of those cells. Finally, there are other cellular mechanisms, such as anaerobic respiration and fermentation, that can also yield ATP.
