| Front | e transport chain |
|---|---|
| Back | - made up of series of e carriers, each with progressively lower energy levels, as excited e moves through chain, it releases energy (used to pump protons accross membrane, creating proton gradient which is maintained by membranes impermeability to protons) - protons move across membrane down conc gradient through hydrophillic channel linked to ATP synthase (catalyses formation of ATP), it releases energy used to form ATP |
