What determines how many mitochandria are in the cell?

Answer 1

Some cells might need more energy than others , and since mitochondria are the powerhouses of a cell, an increased number of mitochondria means higher energy. For example, muscle and sperm cells may need a lot of mitochondria than other cells because of their continuous, rapid movement.

Answer 2

The energy needs of the cell determine the number of mitochondria present. Cells that require a lot of energy, like muscle cells, have more mitochondria. Additionally, factors like cellular stress, exercise, and hormonal signals can also influence mitochondrial biogenesis.
