Here's why:
* Mitochondria are the "powerhouses" of the cell: They are responsible for generating ATP (adenosine triphosphate), the primary energy currency of cells.
* Cellular respiration: Mitochondria are the site of cellular respiration, a process that uses glucose and oxygen to produce ATP. This process involves a series of chemical reactions that break down glucose and release energy.
While other organelles like the cytoplasm and the nucleus play roles in cellular processes, the mitochondria are the primary site of respiration in animals.
