Function of protein pumps of active transport
Web13) The primary function of polysaccharides attached to the glycoproteins and glycolipids of animal cell membranes is A) to facilitate diffusion of molecules down their concentration gradients. B) to actively transport molecules against their concentration gradients. C) to maintain the integrity of a fluid mosaic membrane. WebThe transport proteins have different roles in transport. Channel proteins work during passive transport (diffusion, osmosis). Carrier proteins work during passive transport (facilitated diffusion) and active transport. Pumps work during active transport.
