Question

Electron transport chain step by step explanation

Answer 1

The electron transport chain is made up of a series of spatially separated enzyme complexes that transfer electrons from electron donors to electron receptors via sets of redox reactions. This is also accompanied by a transfer of protons (H+ ions) across the membrane. This leads to the development of an electrochemical proton gradient across the membrane that activates the ATP synthase proton pump, thereby, driving the generation of ATP molecules (energy). The cycle ends by the absorption of electrons by oxygen molecules.
