Detailed explanation-1: -“Facilitated diffusion is a type of diffusion in which the molecules move from the region of higher concentration to the region of lower concentration assisted by a carrier.”
Detailed explanation-2: -Facilitated diffusion. Facilitated diffusion is a process by which solutes diffuse across membranes that they wouldn’t normally get through on their own. They pass through with the aid of transport proteins.
Detailed explanation-3: -All channel proteins and many carrier proteins allow solutes to cross the membrane only passively (“downhill”), a process called passive transport, or facilitated diffusion.
Detailed explanation-4: -In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.
