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 (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.olar molecules and large ions dissolved in water cannot diffuse freely across the plasma membrane due to the hydrophobic nature of the fatty acid tails of the phospholipids that make up the lipid bilayer. Only small, non-polar molecules, such as oxygen and carbon dioxide, can diffuse easily across the membrane.
