Which of these high-energy compounds acts as a reservoir of energy to replenish ATP during high intensity activity of short duration?

Question

Quizplus · Accepted Answer

creatine phosphate is stored in muscle cells and can be rapidly broken down to replenish ATP during short bursts of high intensity activity, such as weight lifting or sprinting. Glycerol and fatty acids are used for energy during longer duration, lower intensity activities. Glycogen is also used for energy, but is primarily stored in the liver and muscles and takes longer to break down into glucose for ATP production.
