membrane proteins


Integral extend into or through the bilayer and are firmly embedded in it
Peripheral proteins associate more loosely with polar heads or with integral proteins on inner or outer surface of bilayer
glycoproteins part carb, part protein
glycocalyx gycoproteins and glycolipids
ion channel(intregral) fluid-filled tunnels
transporters(integral) physically carry molecules across bilayer for glucose
receptors ablity to communicate with specific molecules and alter cell and function
ligand molecule
enzymes(integral) catalysts
linkers(integral) bind cells together-involved with shape change and cell molecule-help with cell stability
gradient difference in something between two areas
concentration the amt of substance in an area
concentration gradient difference in solute concentration between two area
movement of molecule from [High] to [low] solute moves down the concentration gradient
molecule from[low] to [high] mean the concentration gradient moves up the concentration gradient
electrical gradient unequal ion charged distribution--difference in electrical charge between two areas
electrochemical gradient ion or molecule influenced by both [ ] amd electrical gradient
