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.
Tutorial to help answer the question. A. Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. B. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient. C. Simple diffusion is not saturable; facilitated diffusion rates are limited by the number of functional membrane proteins and can be saturated*.
