The process by which ATP is produced in the inner membrane of a mitochondrion. The electron transport system transfers protons from the inner compartment of the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP.
(1) Chemiosmosis

(2) Phosphorylation

(3) Glycolysis

(4) Fermentation
