Vedclass · Answer

(A) The correct option is $A$.In the electron transport system $(ETS)$ located in the inner mitochondrial membrane:$1$. Coenzyme $Q$ (ubiquinone),labeled as $A$,acts as a mobile electron carrier that transfers electrons from Complex $I$ ($NADH$ dehydrogenase) and Complex $II$ (succinate dehydrogenase) to Complex $III$ (cytochrome $bc_1$ complex).$2$. Cytochrome $c$,labeled as $B$,is a small protein attached to the outer surface of the inner membrane and acts as a mobile carrier for electrons between Complex $III$ and Complex $IV$ (cytochrome $c$ oxidase).

The following is a scheme showing the electron transport system. Identify the electron carrier molecules indicated as $A$ and $B$. Choose the correct option.
