Facilitated Diffusion and Active Transport

Vedclass · Answer

(B) $1$. Simple diffusion is a passive process that does not require membrane proteins.$2$. Facilitated diffusion involves the movement of molecules across a membrane through specific transport proteins without the expenditure of energy.$3$. Active transport involves the movement of molecules against the concentration gradient,which requires both energy $(ATP)$ and specific membrane transport proteins (pumps).$4$. Therefore,both facilitated diffusion and active transport require membrane proteins for the transport of substances.

$S.no.$	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
