Oxidative Phosphorylation

• Oxidative phosphorylation takes place on the inner folded membrane (cristae) of this mitochondrion
• This phase requires oxygen and is therefore an aerobic phase
• H-atoms from Krebs cycle are carried to a hydrogen transfer system by coenzymes
• H-atoms are transferred from on hydrogen acceptor to the next
• Every time as H-atom is transferred to a acceptor, energy is released
• This energy binds a phosphate (P) molecule and ADP to form ATP, which is the energy carrier in the cell
• Oxygen is the final hydrogen acceptor. Two hydrogen atoms combine with one oxygen atom to form a molecule of water (H2O)
