Facilitated diffusion

Vedclass · Answer

(B) Facilitated diffusion is a process of passive transport where molecules move across the cell membrane with the help of special membrane proteins (carrier proteins or channel proteins).It is highly selective,meaning it allows only specific molecules to pass through.It does not require metabolic energy $(ATP)$ because the movement occurs along the concentration gradient (from a region of higher concentration to a region of lower concentration).

Identify a type of molecular movement which is highly selective and requires special membrane proteins,but does not require energy.
