Vedclass · Answer

(A) Cytochrome $c$ is a small protein attached to the outer surface of the inner mitochondrial membrane.It acts as a mobile electron carrier for electron transfer between Complex $III$ (cytochrome $bc_1$ complex) and Complex $IV$ (cytochrome $c$ oxidase).Since it is loosely associated with the membrane surface and not embedded within the lipid bilayer,it is classified as a peripheral membrane protein.It is located on the side of the inner mitochondrial membrane that faces the intermembrane space (perimitochondrial space).Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

Column-$I$ ($ETS$ Complex)	Column-$II$ (Name of Complex)
$P$. Complex-$I$	$I$. Cytochrome $c$ oxidase complex
$Q$. Complex-$II$	$II$. Cytochrome $bc_1$ complex
$R$. Complex-$III$	$III$. $ATP$ synthase complex
$S$. Complex-$IV$	$IV$. $FADH_2$ dehydrogenase complex
$T$. Complex-$V$	$V$. $NADH$ dehydrogenase complex

$A$ : Cytochrome $c$ is a peripheral protein.
$R$ : It is found attached on the perimitochondrial space side of the inner mitochondrial membrane.
