Facilitated diffusion does NOT require energy. It is facilitated because of the help of a transport protein, but the molecules are still going down the concentration gradient. Facilitated diffusion does NOT require energy, as it is still going down the concentration gradient. diffusion does NOT require energy. diffusion is not a form of active transport.
Facilitated Diffusion. this form of diffusion is regulated by protein channels in the membrane and requires no energy input from the cell. Active Transport. movement of molecules or ion into or out of the cell against its concentration gradient (from low to high) and requires an input of energy.
