Vedclass · Accepted Answer

Active transport requires energy.

Vedclass · Answer

(D) Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration (against the concentration gradient). This process requires the expenditure of metabolic energy in the form of $ATP$.In contrast,passive transport (such as diffusion or facilitated diffusion) occurs along the concentration gradient (from higher to lower concentration) and does not require energy expenditure.

Column-$I$	Column-$II$
$(a)$ Passive transport	$(p)$ Movement from higher concentration to lower concentration, no energy required
$(b)$ Active transport	$(q)$ Movement along the concentration gradient, requiring carrier proteins
$(c)$ Facilitated diffusion	$(r)$ Movement against the concentration gradient, requiring energy
$(d)$ Osmosis	$(s)$ Diffusion of solvent molecules across a semi-permeable membrane
