Here's why:
* Mitochondria are the powerhouses of the cell. They are responsible for cellular respiration, the process that converts glucose (sugar) into ATP (adenosine triphosphate), the primary energy currency of cells.
* Cells with high energy demands need a lot of ATP to carry out their functions. This includes cells like muscle cells (for contraction), nerve cells (for transmitting signals), and cells in the liver (for detoxification).
* More mitochondria means more ATP production, allowing the cell to meet its energy needs.
