Oxidative Phosphorylation

• Oxidative Phosphorylation occurs in the matrix and intermembrane space
• During Oxidative Phosphorylation, reduced NAD and FAD release H+ ions splitting into protons and electrons
• Electrons split in Oxidative Phosphorylation go through the electron transfer chain, producing energy for active transport of H+ ions into matrix, creating an electrochemical gradient
• H+ Ions transported into the matrix during Oxidative Phosphorylation move down the concentration gradient via facilitated diffusion through ATP Synthase, changing the shape of the protein to release energy catalysing ATP production
• Oxygen acts as the final electron acceptor in Oxidative Phosphorylation, picking up electrons and H+ ions to produce water
• Net Gain of Oxidative Phosphorylation = 34x ATP
