The main energy for prolonged muscle work comes from ____.
A)stored ATP
B)stored creatine phosphate
C)fermentation of carbohydrates
D)aerobic respiration of carbohydrates and fats
E)stored ADP

Question

Quizplus · Accepted Answer

Prolonged muscle work requires energy that is sustained for longer periods of time, which is primarily provided by aerobic respiration of carbohydrates and fats. Stored ATP and creatine phosphate can provide immediate energy for short bursts of muscle activity, and fermentation of carbohydrates can provide energy during anaerobic exercise, but these sources are not sufficient for prolonged muscle work. Stored ADP is not a source of energy.
