The enzyme cytochrome oxidase is inhibited by which of the following?

In the $ETS$ (Electron Transport System),how many molecules of each cytochrome are required for the transfer of $2$ $e^-$?

Match the following columns regarding the Electron Transport System $(ETS)$:

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

State the path of $H^+$ for the synthesis of $ATP$ by $ATP$ synthase.
