During moderate but prolonged exercise, most of the energy for contraction is supplied by
A) creatine phosphate.
B) aerobic respiration.
C) anaerobic respiration.
D) fermentation.
E) glycolysis.

Question

Quizplus · Accepted Answer

During moderate but prolonged exercise, the body relies primarily on aerobic respiration for energy production. This is because aerobic respiration can produce a large amount of ATP over a longer period of time compared to anaerobic respiration or fermentation. Creatine phosphate and glycolysis are also used during exercise but are not the primary sources of energy during moderate, prolonged activity.
