Mitochondria are organelles within cells responsible for aerobic respiration, the process by which oxygen is used to generate energy in the form of ATP. During aerobic respiration, mitochondria utilize oxygen to break down glucose and other molecules, releasing energy. This energy is then used to power cellular activities, including the active transport of oxygen into cells through various membrane transporters, ensuring its availability for mitochondrial respiration.
