      The Electron Transport Chain is also called the respiratory chain. It is the last stage in aerobic respiration and is also in the mitochondria. The Electron Transport Chain is oxidative phosphorylation by the chimiosmosis of ADP. The coenzyme transports their electrons and H+ ions to the cristae, after they reduce NADH and FADH2. The Electron Transport Chain is really a series of election transporters and multi enzymes. All these proteins and enzymes oxidize NADH+ and FADH2. Once the excess electrons have been removed the H+ ions are as well. Now this allows NAD and FAD to return to reactions in the matrix.

     When the electron transporters in the respiratory chain are oxidized and reduced, small amounts of energy is given off. This energy6 is then used to energize the proton pumps that pump the H+ ions across the internal membrane into the intermediate space. These ions are inclosed between two membranes, so a concentration gradient is created. When the H+ ions move through ATP synthase, it helps the synthesis of ATP.

     Almost all the ATP production is made in the Electron Transport Chain. This phase gives enough energy for mammals or other organisms to maintain body temperature and keep up with other demands of energy. In total the Electron Transport Chain makes 36(38) ATP.
