Active transport

Vedclass · Answer

(A) Active transport is the process of moving molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration,which is against the concentration gradient.This process requires energy in the form of $ATP$ to move substances against their electrochemical gradient.In contrast,diffusion and osmosis are passive processes that occur along the concentration gradient and do not require energy.

Column-$I$	Column-$II$
$(A)$ Movement of ions into or out of the cell	$(1)$ Diffusion
$(B)$ Outward movement is	$(2)$ Flux
$(C)$ Inward movement is	$(3)$ Efflux
$(D)$ Passive uptake	$(4)$ Influx

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

The movement of ions against the concentration gradient is called ........
