Are protein channels needed for facilitated diffusion? To facilitate these transfer of substances across the membrane, certain integral membrane proteins or the transmembrane proteins are required. They are channel proteins and carrier proteins.
Does facilitated diffusion require a channel or carrier? In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
What type of transport requires a protein channel? Both active transport and facilitated diffusion do use proteins to assist in transport. However, active transport works against the concentration gradient, moving substances from areas of low concentration to areas of high concentration.
What is required for facilitated diffusion to occur? Facilitated diffusion requires membrane proteins to transport biological molecules. Simple diffusion is one that occurs unassisted by membrane proteins. Since membrane proteins are needed for transport in facilitated diffusion, the effect of temperature is often more pronounced than in simple diffusion.
