Vedclass · Answer

(A) In the Electron Transport System $(ETS)$ located in the inner mitochondrial membrane,various complexes are involved in the transfer of electrons.Complex $I$ is $NADH$ dehydrogenase,which accepts electrons from $NADH + H^+$.Complex $II$ is succinate dehydrogenase (which uses $FADH_2$).Complex $III$ is cytochrome $bc_1$ complex.Complex $IV$ is cytochrome $c$ oxidase,which contains cytochromes $a$ and $a_3$ and two copper centers.Therefore,complex $I$ is $NADH$ dehydrogenase and complex $IV$ is cytochrome $c$ oxidase.

In $ETS$,complexes $I$ and $IV$ are respectively:
