【多选题】Why is the chemiosmotic mechanism for ATP synthesis called oxidative phosphorylation?
A.
The chemiosmotic generation of energy begins when the activated carriers NADH and FADH 2 donate their electrons to the electron-transport chain in the inner mitochondrial membrane, becoming oxidized to NAD + and FAD, respectively, in the process.
B.
The electrons are quickly passed along the chain to molecular oxygen (O 2 ) to form water (H 2 O). The stepwise movement of these electrons through the components of the electron-transport chain releases energy that can then be used to pump protons across the inner mitochondrial membrane .
C.
The resulting proton gradient, in turn, is used to drive the synthesis of ATP. The inner mitochondrial membrane thus serves as a device that converts the energy contained in the high-energy electrons of NADH (and FADH 2 ) into the phosphate bond of ATP molecules.
D.
This chemiosmotic mechanism for ATP synthesis is called oxidative phosphorylation because it involves both the consumption of O 2 and the addition of a phosphate group to ADP to form ATP.
