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.
Answer:
D.
Explanation:
The periodic table is divided into vertical periods and horizontal groups
Valence electrons are the electron on the outer energy level and they are important because they tell if that element is compatable
