Electron-shuttling
WebThe electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH 2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water. The electron transport … WebThe electron transport chain. Electrons enter from NADH to complex I or succinate dehydrogenase, which is complex II. Electrons derived from glycolysis through the glycerol-3-phosphate shuttle, complex I, and complex II join at coenzyme Q and are transferred to oxygen as shown. As electrons pass through complexes I, III, and IV, protons are ...
