Electron Transport Chain Stats and Facts

Electron Transport Chain In Depth
Simply:
1. Energy is transferred to a chain of proteins in the inner membrane of the mitochondrion.
2. A large number of ATP molecules are made. Oxygen enters the process and is used to make water molecules. Water and heat are given off as waste products.
More complexly:
1. Proteins, specifically, 2 molecules of NADH and a molecule of FADH2, pick up high-energy electrons inside the inner membrane of the mitochondria.
2. As the high-energy electrons travel through the proteins, the proteins use their energy to pump hydrogen ions across the inner membrane, causing them to pile up on the inside of the mitochondria's inner membrane.
3. The stream of hydrogen ions diffuses through a protein channel in the ATP synthase enzyme, which adds phosphate groups to ADP, turning it into ATP molecules. For every two electrons that go into the electron transport chain, about 3 ATP are made.
4. Water (a waste product here) is created when oxygen comes into the cellular respiration process, picking up electrons and hydrogen ions to form H2O.
