Question

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.

Answer 1

Cellular respiration rates would increase in the indivuals cells correctly describes a benefit of this abillity

Answer 2

The correct answer is option a. Cellular respiration rates would increase in the individual’s cells.

The mitochondria is the site of the cellular respiration in the cells. in case, the mitochondria are present in more number in the cells, the cells would have an enhanced rate of cellular respiration, and would provide more energy through rapid production of ATP molecules in the muscle cells. In the muscle cells, the regular exercise increases the need of cellular respiration, that is why, the muscle cell increases the number of mitochondria, if they are involved in regular exercise.
