a. By the oxidation of NADH in complex I b. Electrons from succinate pass through a flavoprotein with the cofactor FAD and several Fe-S centers (in Complex II) on the way to Q c. 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 Q. d. Acyl-CoA dehydrogenase (the first enzyme of oxidation) transfers electrons to electron- transferring flavoprotein (ETF), from which they pass to Q via ETF
