Compare the following processes of transport and choose the correct option:

$S.no.$	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

In cell transport,the difference between permeable transport and bulk transport relates to:

Identify the following process and choose the correct option.

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