Facilitated diffusion

Vedclass · Answer

(B) $1$. Simple diffusion occurs along the concentration gradient but does not require carrier proteins.$2$. Facilitated diffusion occurs along the concentration gradient and requires specific carrier proteins to transport molecules across the membrane.$3$. Active transport requires energy $(ATP)$ and moves molecules against the concentration gradient.$4$. Therefore,diffusion mediated by carrier molecules along the concentration gradient is called Facilitated diffusion.

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
