Simple diffusion – A process of diffusion that occurs without the aid of an integral membrane protein. Allows substances to pass through cell membranes without any energy. crypto key generate rsa是什么意思WebFacilitated transport. In facilitated transport, also called facilitated diffusion, material moves across the plasma membrane with the assistance of transmembrane proteins down a concentration gradient (from high to low concentration) without the expenditure of cellular energy.
