| Polar molecules | Need facilitated diffusion |
| Solutes attracts | attract solvent |
| Inhibitory are ligand gated ion channels that are permeable to only K+ and Cl- (chlorine | Moves mebrane potential further from threshold, and both chlorine and potassium comes in |
| Excitatory are ligand gated ion channels that are permeable to both K+ and Na+ | bring membrane potential towards threshold |
