Oxidative Phosphorylation - Ecu

• Oxidative Phosphorylation: NADH and QH 2are oxidizedby the respiratory electron transport chain (ETC).• ETC is set of membrane-embedded protein complexesthat act as electron carriers, passing electrons fromNADH and QH 2to molecular oxygen.• As electrons move through the complexes, protons aretransported across the inner mito. membrane from thematrix to the intermembrane space.• The energy stored in this ion gradient is used tosynthesize ATP from ADP and Pi by a membranebound ATPase.Chemiosmotic Theory : Formulated by PeterMitchell in the 1960’s. Nobel Prize for this workawarded in 1978.
