Facilitated diffusion

Vedclass · Answer

(B) The image illustrates a molecule moving across a cell membrane with the help of a carrier protein. $1$. Diffusion occurs directly through the lipid bilayer without the aid of proteins. $2$. Facilitated diffusion involves the movement of molecules across the membrane with the help of special membrane proteins (carrier proteins or channel proteins) along the concentration gradient. $3$. Active transport requires energy $(ATP)$ to move molecules against the concentration gradient. Since the diagram shows the involvement of a carrier protein to facilitate the movement of molecules,it represents facilitated diffusion.
