What is the electron transport chain?
• a stage in which NADH and FADH2 give up their electrons to drive the production of many ATP molecules

a process in which ATP gives up its phosphate group to produce NADH and FADH2, which are required by the
citric acid cycle

•a process in which ATP gives up its phosphate group to drive the production of cell processes

•a stage in which NAD+ and FAD give up their electrons to produce water needed by cells
