Some muscle cells have the ability to produce more mitochondria if they are involved in regular exercise. which answer correctly describes a benefit of this ability? a) cellular respiration rates would increase in the individual's cells. b) the individual would not need as much food as before. c) more fat molecules would be burned by the individual. d) the individual's mass would increase due to the excess mitochondria.

The correct option is A) Cellular respiration rates would increase in the individual's cells.

Explanation:

As the muscle cells carry out the exercise, they need more oxygen to respire. This process will give them energy in the form of ATP to carry out the workout. As the process of cellular respiration occurs in the mitochondria, hence an increase in mitochondria of a cell results in increased amount or respiration.

Mitochondria are known as the powerhouse of a cell because they can produce ATP by the process of respiration. Hence, option A is correct.

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
