Answer:
Dropping in energy levels
Against their concentration gradient
Explanation:
The pair of electrons are passed down a series of electron carriers of progressively lower energy levels through a series of redox reactions in the electron transport chain, releasing energy (electrical potential energy) to be used by H+ pump for the active transport of H+ ions (aka protons) from a region of higher concentration to a region of lower energy level against its concentration gradient.
