Acetyl CoA reacts with oxaloacetic acid. All molecules of NADH and FADH2 generated by the process donate electrons to an electron transport chain. ATP is produced as succinyl CoA is converted into succinic acid. Citric acid is formed and undergoes a series of oxidative decarboxylations before being changed into succinyl CoA. Electrons from NADH and FADH2 are passed from one acceptor to the next in a series. Electrons leaving the electron transport chain are accepted by O2. FAD turns into FADH2 as it accepts H+ and electrons from succinic acid. Fumaric acid is formed and repeatedly oxidized until it changes into oxaloacetic acid. Glucose breaks down into two molecules of pyruvate, accompanied by the production of ATP and NADH. O2 combines with H+ to form water. Pyruvate is oxidatively decarboxylated and converted into acetyl CoA. The energy released by the electrons as they transfer from one acceptor to the next is used to generate ATP. Two phosphate groups from two ATP molecules energize a molecule of glucose.
