membrane proteins
types
| Question | Answer |
|---|---|
| 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 |
