Vedclass · Answer

(D) Membrane proteins are essential for the movement of hydrophilic substances across the lipid bilayer.Facilitated diffusion involves the use of membrane proteins (channels or carriers) to move molecules along the concentration gradient without the expenditure of energy.Active transport also utilizes membrane proteins (pumps) to move molecules against the concentration gradient,which requires energy in the form of $ATP$.Therefore,both facilitated transport and active transport rely on membrane proteins.
