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.
Whether all cases of facilitated diffusion of small molecules use channels is yet to be proven. Perhaps some molecules are passed through the membrane by a conformational change in the shape of the transmembrane protein when it binds the molecule to be transported.ctive transport is the pumping of molecules or ions through a membrane against their concentration gradient. It requires: 1  a transmembrane protein (usually a complex of them) called a transporter and. 2  energy. 3  The source of this energy is ATP.
