What's the Difference Between Diffusion and Facilitated Diffusion
In diffusion and osmosis substances move down a concentration gradient. Facilitated diffusion is for polar or charged molecules which are relatively small in size while diffusion is for small particles which are neither polar nor charged that need to cross the cell membrane. Passive Vs Active Transport Membrana Celular Ap Biology Transporte Passivo Simple diffusion is most often involved in the flow of non-polar molecules that are small in size. . Explain the difference between simple diffusion across a membrane facilitated diffusion and active transport. Diffusion across a cell membrane is a type of passive transport or transport across the cell membrane that does not require energy. The main difference between facilitated diffusion and active transport is that facilitated diffusion occurs through a concentration gradient whereas active transport occurs against the concentration gradient by using energy from ATP. 2Facilit
