Quizplus · Accepted Answer

All three energy systems are active at all times, with the contribution of each varying depending on the intensity and duration of the activity. Additionally, all three systems replenish ATP by rephosphorylation. The systems also vary in terms of speed of action, amount of ATP replenished, and duration of action. However, one system is not "switched on" while the others are "switched off."
