Vedclass · Answer

(D) In the Electron Transport System $(ETS)$,mobile electron carriers are essential for transferring electrons between fixed protein complexes.$1$. Ubiquinone $(UQ)$ is a lipid-soluble mobile carrier that transfers electrons from Complex $I$ and Complex $II$ to Complex $III$ in the mitochondrial inner membrane.$2$. Plastoquinone $(PQ)$ is a mobile carrier in the thylakoid membrane of chloroplasts that transfers electrons from Photosystem $II$ to the Cytochrome $b_6f$ complex.$3$. Cytochrome $c$ $(Cyt\,c)$ is a small,water-soluble protein that acts as a mobile carrier,transferring electrons from Complex $III$ to Complex $IV$ in the mitochondria.Since all three are mobile electron carriers,the correct answer is $D$.

Column $I$	Column $II$
$i.$ $FADH_2$	$a.$ Complex $III$
$ii.$ Ubiquinol	$b.$ Complex $IV$
$iii.$ $NADH + H^{+}$	$c.$ Complex $II$
$iv.$ Cytochrome $C$	$d.$ Complex $I$
