Vedclass · Answer

(A) In the electron transport system $(ETS)$ of oxidative phosphorylation,electrons are passed through a series of complexes. At the end of the chain,the final electron acceptor is oxygen $(O_2)$. Oxygen accepts the electrons and combines with protons $(H^+)$ to form water $(H_2O)$. This process is essential for maintaining the flow of electrons through the transport chain.

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 $I$
