<P> During oxidative phosphorylation , electrons are transferred from electron donors to electron acceptors such as oxygen , in redox reactions . These redox reactions release energy , which is used to form ATP . In eukaryotes , these redox reactions are carried out by a series of protein complexes within the inner membrane of the cell 's mitochondria , whereas , in prokaryotes , these proteins are located in the cells ' intermembrane space . These linked sets of proteins are called electron transport chains . In eukaryotes , five main protein complexes are involved , whereas in prokaryotes many different enzymes are present , using a variety of electron donors and acceptors . </P>
