A mitochondrion 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. They were discovered by Albert von Kölliker in 1857 in the voluntary muscles of insects. The term mitoc… WebMitochondria are energy-producing organelles found in most living cells. They use carbohydrates such as glucose in chemical reactions based on an electron transport chain and the citric acid cycle. The final products of these reactions are water and ATP, an energy-storage molecule.
