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.
Most cellular functions need energy to be carried out: synthesis of proteins, synthesis of membranes, movement of the cell, cellular division, etc. need energy in order to be made. The ATP is the molecule that carries energy to the place where the energy is needed. When ATP breaks into ADP (Adenosine diphosphate) and Pi, the breakdown of the last covalent link of phosphate (a simple -P04) liberates energy that is used in reactions where it is needed.
