Determine which complex of the electron transport chain (respiratory chain) each phrase describes. (coenzyme q is also called ubiquinone or ubiquinol, depending on whether it is in oxidized or reduced form.)complex i: complex ii: complex iii: complex iv: here are the choices that need to be put in the correct complex: 1) nadh-ubiquinone(nadh-coenzyme q oxidoreductase)2) coenzyme q-cytochrome c oxidoreductase3)electron transfer from succinate to ubiquinone (coenzyme q)4) electron transfer from cytochrome c to o25) succinate-coenzyme q oxidoreductase (succinate dehydrogenase)6) cytochrome c oxidase7) electron transfer from ubiquinol (qh2) to cytochrom c8) electron transfer from nadh to ubiquinone (coenzyme q)
