Question

Quizplus · Accepted Answer

During aerobic exercise, such as power-walking, the primary fuel sources are fatty acids and glucose. Amino acids are not typically used as a fuel source during exercise unless extreme conditions such as starvation occur. Therefore, option A and C are not the best choices. Glucose alone is not enough to sustain the body during aerobic exercise and would quickly deplete, making option D incorrect. Hence, option B is the best choice.
