Living organisms catabolize organic molecules within their cells and use the energy released to manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve oxidation of foodstuffs, yet only the latter requires oxygen.
Cellular respiration is a very complex process that consists of many steps that take place inside the cell, in an organelle called a mitochondrion. Mitochondria are responsible for converting digested nutrients into the energy-yielding molecule adenosine triphosphate (ATP) to fuel the cell's activities. This function, known as aerobic respiration, is the reason mitochondria are frequently referred to as the powerhouse of the cell. There are two types of respiration that occur in cells to produce energy. When oxygen is available in the cell, aerobic respiration, as mentioned previously, occurs. When oxygen is not readily......
