Vedclass · Answer

(D) Facilitated diffusion is a type of passive transport that occurs across the cell membrane with the help of special membrane proteins.These proteins provide a pathway for specific molecules or ions to move across the membrane along their concentration gradient without the expenditure of metabolic energy $(ATP)$.Aquaporins are specialized integral membrane proteins that act as channels for the facilitated diffusion of water molecules across the cell membrane.Therefore,aquaporins are responsible for facilitating the movement of water in cells.
