Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration. Facilitated diffusion is a passive process: The solutes move down the concentration gradient and don't use extra cellular energy to move. Channel proteins are another type of facilitated diffusion that allow the selective transport of one type of hydrophilic molecule across the cell membrane. Types of active transport are Proton pumps, Exocytosis, Sodium-potassium pumps, and Endocytosis while passive transport is filtration, osmosis, and diffusion. Passive transport is meant to maintain balance and equilibrium within or outside the cell whereas active transport to carry ions and molecules. Jul 25, 2019 · Passive transport usually occurs down a concentration gradient. Essentially what this means is that molecules will move from areas where there are more of them to where there are fewer of them. When particles move down their concentration gradient from an area of high concentration to low concentration, this is called (simple) diffusion.
