Determine which complex of the electron transport chain(respiratory chain) each phrase describes. (Coenzyme Q is alsocalled ubiquinone or ubiquinol, depending on whether it is inoxidized or reduced form.)

Complex I:

Complex II:

Complex III:

Complex IV:

Here are the choices that need to be put in the correctcomplex:

1) NADH-ubiquinone(NADH-coenzyme Q oxidoreductase)

2) coenzyme Q-cytochrome c oxidoreductase

3)electron transfer from succinate to ubiquinone (coenzymeQ)

4) Electron transfer from cytochrome c to O2

5) Succinate-coenzyme Q Oxidoreductase (succinatedehydrogenase)

6) cytochrome c oxidase

7) electron transfer from ubiquinol (QH2) to cytochrom c

8) electron transfer from NADH to ubiquinone (coenzyme Q)

Answer rating: 100% (QA)
