Question

Which statement best explains why the level of ATP in skeletal muscles changes during exercise?
Adenosine and phosphate in ATP are destroyed by the muscles.
Waste ATP accumulates in the blood stream rather than in the muscles.
The mitochondria increases ATP production in the muscles.
ATP is used for energy faster than it can be produced in the muscles.

Answer 1

ATP or the Adenosine Triphosphate is referred to as the basic energy unit of the body. In the case of doing an exercise, what happens is that, the more someone increases his or her activity, the more energy is required and the body should compensate for this need. Therefore, the answer for this would be option D.
