which statement is false? a. Electrons do not usually flow through the electron-transport chain to oxygen unless ADP is simultaneously phosphorylated to ATP. b. Oxidative phosphorylation requires a supply of NADH or other source of electrons at high potential, oxygen, and ADP. c. The rate of oxygen consumption by mitochondria increases markedly when ADP is added and then returns to its initial value when the added ADP has been converted into ATP. d. The most important factor in determining the rate of oxidative phosphorylation is the level of ADP and inorganic phosphate
