The response of ATP concentration in the muscle to exercise reveals a relatively large proportion of the ATP stored in the muscle is not able to be used for force production, even during very high-intensity exercise.

Question

Quizplus · Accepted Answer

This is true. During exercise, the ATP stored in the muscle is used for force production, but some of it cannot be accessed and remains stored in the muscle. This is why other energy systems, such as the phosphocreatine system and glycolysis, are also utilized during high-intensity exercise to generate additional ATP.
