oxidative phosphorylation


The metabolism of glucose through glycolysis and the Krebs cycle yields six carbon dioxide molecules, and a net production of 6 ATPs per molecule of glucose. The majority of the chemical potential energy of the glucose molecule has been transfered to the NADH and FADH2 molecules in the form of high energy electrons. It is from this energy that the majority of the ATP will be synthesized.

The energy of these high energy electrons will be released via the electron transport chain located mainly in the inner mitochondrial membrane in eucayotic organisms or in the plasma membrane of most procaryotes.
