Unformatted text preview: • Oxygen gains the electrons because it is highly electronegative. • Electron carriers are dinucleotides that come from B vitamins in diet. It becomes NADH. • NADH then carries the electrons to the electron transport chain. It then starts all over again. • The process of cellular respiration there is an energy investment stage that gets the electrons ready to be stripped off. • NAD+ is the oxidized form. It has dropped off its electrons. • NADH contains more free energy. It carries the electrons that will be stripped and be used to do work. • As the electrons fall gently down, there is a controlled release of energy for synthesis of ATP....
