During oxidative phosphorylation of cell respiration, H+ ions move through the membrane pumping electrons from one side of the membrane to the other. ATP is synthesized when H+ ions move through a protein channel provided by ATP synthase. ATP pushes electrons through membrane carriers creating a H+ ion gradient. a concentration gradient is generated when large numbers of H+ ions passively diffuse from the matrix of the mitochondrion to the mitochondrion's intermembrane space. a phosphate is transferred from an organic molecule to ADP.

The immediate energy source that drives ATP synthesis by ATP synthase during oxidative phosphorylation is the (A) oxidation of glucose and other organic compounds. (B) flow of electrons down the electron transport chain. (C) H' concentration gradient across the membrane holding ATP synthase. (D) transfer of phosphate to ADP.
