The movement of high-energy electrons down the electron transport chain leads to theelectrons oxidizing existing molecules of water.mitochondrial membrane becoming heavily electrically charged.formation of a proton gradient.electrons oxidizing existing molecules of carbon dioxide.

Answer 1

The movement of high-energy electrones down the electron transport chain leads to the formation of a proton gradient.

This process is part of what is known as oxidative phosphorylation, a process in which the electron transport chain forms a proton gradient across the inner mitochondrial membrane which finally sinthesises ATP.
