Here's why:
* Mitochondria are the powerhouses of the cell: They are responsible for producing ATP, the energy currency of cells.
* Cellular respiration is the process of converting glucose into ATP: This process involves a series of chemical reactions that take place within the mitochondria.
* Mitochondria have specialized compartments: They have an inner membrane, an outer membrane, and a matrix, each of which plays a role in different steps of cellular respiration.
So, while cellular respiration begins in the cytoplasm, the majority of the process occurs within the mitochondria.
