Only $I$

Vedclass · Answer

(D) $1$. Facilitated diffusion and active transport are highly specific because they use carrier proteins to select substances. Simple diffusion is not specific.$2$. Active transport requires $ATP$ energy to move substances against the concentration gradient. Facilitated diffusion and simple diffusion do not require $ATP$.$3$. Saturation occurs in facilitated diffusion and active transport because they rely on a limited number of carrier proteins. Simple diffusion does not show saturation.$4$. Facilitated diffusion and active transport require transport proteins,whereas simple diffusion does not.Comparing these facts with the provided table,none of the rows are entirely correct as presented in the original prompt's table. However,based on standard biological principles,$I$ is the only property that correctly identifies the specificity of these processes.

$S.no.$	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
