| I: | The F1 headpiece is peripheral membrane protein complex and contains the site for the synthesis of ATP from ADP and inorganic phosphate. |
| II: | The F0 is an integral membrane protein complex that forms the channel through which protons cross the inner membrane. |
| III: | For each ATP produced, 4H+ passes through F0 from the intermembrane space to the matrix down the electrochemical proton gradient. |
