Vedclass · Answer

(D) Passive transport is the movement of molecules across a cell membrane without the expenditure of metabolic energy $(ATP)$.Diffusion is a passive process where molecules move from a region of higher concentration to a region of lower concentration.Facilitated diffusion is also a passive process that uses specific membrane proteins to move molecules across the membrane without the use of $ATP$.Active transport,on the other hand,requires the expenditure of energy $(ATP)$ to move molecules against their concentration gradient.Therefore,both diffusion and facilitated diffusion are types of passive transport.

Column-$I$	Column-$II$
$P$. Diffusion	$I$. Along the gradient, with protein
$Q$. Facilitated transport	$II$. Against the gradient
$R$. Active transport	$III$. Along the gradient, without protein
