Quizplus · Accepted Answer

When an athlete exhausts his or her ATP supply, catabolic processes are activated that generate ATP. This process involves breaking down glucose and other stored molecules to generate energy in the form of ATP to meet the cell's energy demands. This process is called cellular respiration. Therefore, the best choice is B.
