Figure 18-9 Path of electrons from NADH, succinate, fatty acyl-CoA, and glycerol-3-phosphate to ubiquinone (UQ). Electrons from NADH pass through a flavoprotein to a series of iron-sulfur proteins (in Complex I) and then to UQ. Electrons from succinate pass through a flavoprotein and several Fe-S centers (in Complex II) on the way to UQ. Glycerol-3-phosphate donates electrons to a flavoprotein (glycerol-3-phosphate dehydrogenase) on the outer face of the inner mitochondrial membrane, from which they pass to UQ. Acyl-CoA dehydrogenase (the first enzyme in β oxidation) transfers electrons to electron-transferring flavoprotein (ETFP), from which they pass via ETFP-ubiquinone oxidoreductase to UQ.
