The electron transport chain converts energy stored in hydrogen ions and various other substances formed in early cellular respiration to produce high energy ATP in mitochondria. Mitochondria contain both an inner and an outer membrane, and it is along the inner membrane that the actual reactions of the chain occur. Inside the inner membrane a surplus of hydrogen ions is created that produces a concentration gradient across the membrane to the intermembrane space. This gradient causes a force that pushes hydrogen ions out of the innermost matrix and into the intermembrane space. This exchange occurs through special proteins called ATP synthase that convert low energy ADP into high energy ATP whenever a hydrogen ion is sent through one. When all is said and done, the excess electrons and hydrogen are bonded to oxygen to form water molecules.
