Hace 4 días · A mitochondrion ( / ˌmaɪtəˈkɒndriən /; [1] pl.: mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. [2] .
