WebPassive Process: Simple diffusion, Facilitated diffusion, Osmosis The cellular plasma membrane is selectively permeable, which means some materials move through it while others cannot. The movement of materials into and out of the cell is called membrane transport. This activity will help you identify the different mechanisms of membrane … Webfacilitated diffusion: the protein-mediated transport of a compound across a biomembrane that is not ion-driven; a saturable transport system. Synonym(s): passive transport WebDespite the help of transport proteins, facilitated diffusion is considered passive transport because the solute is moving down its concentration gradient, a process that requires no energy. Facilitated diffusion speeds transport of a solute by providing efficient passage through the membrane, but it does not alter the direction of transport. grey valance at walmart
