A cell has enough available ATP to meet its needs for about 30 seconds. What is likely to happen when an athlete exhausts his or her ATP supply?
A) He or she has to sit down and rest.
B) Catabolic processes are activated that generate more ATP.
C) ATP is transported into the cell from the circulatory system.
D) Other cells take over, and the muscle cells that have used up their ATP cease to function.

Question

Quizplus · Accepted Answer

When an athlete exhausts his or her ATP supply, catabolic processes are activated that generate more ATP. These processes include the breakdown of glucose and other nutrients through cellular respiration pathways such as glycolysis, the citric acid cycle, and oxidative phosphorylation. This allows the cells to continue functioning and generating energy despite the depletion of their initial ATP reserves.
