Vedclass · Answer

(A) Active transport is a mechanism by which molecules or ions are moved across a cell membrane from a region of lower concentration to a region of higher concentration.Because this movement is against the concentration gradient,it requires the expenditure of metabolic energy,typically in the form of $ATP$.Therefore,Statement $S$ is true because energy is consumed,and Reason $R$ is true because it correctly explains why energy is required (movement against the gradient).Thus,$R$ is the correct explanation of $S$.

$S.no.$	Property	Facilitated diffusion	Active Transport	Simple Diffusion
$I.$	Highly specific	Yes	Yes	No
$II.$	Energy as $ATP$	No	Yes	No
$III.$	Saturation point reached when all carrier proteins are used	Yes	Yes	No
$IV.$	Require transport proteins	Yes	Yes	No

$S -$ Statement: Energy is consumed during active transport.
$R -$ Reason: This transport occurs against the concentration gradient of the substances.
