Ecco perché:

* Mitochondria are the "powerhouses" of the cell. Their primary function is to produce ATP (adenosine triphosphate), the cell's main energy currency.

* Food storage is typically handled by other organelles. In animal cells, glycogen is the primary storage form of glucose and is stored in the cytoplasm. In plant cells, carbohydrates are stored as starch in plastids, such as amyloplasts.

While the mitochondria uses nutrients like glucose to produce energy, it does not store them.
