  • Move substances down their concentration gradient
  • 3 types
    • Ungated
      • Always open
      • e.g. K+-channel
    • Voltage-gated
      • Open in response to changes in membrane voltage
      • Na Channel
      • Ca Channel
    • Ligand-gated
      • Open in response to a ligand
      • e.g. post-synaptic membrane receptors
        • NMDA receptor
        Glutamate
        Gaba receptor
        GABA
        Nicotinic acetylcholine receptor
        Nicotine

    • Secondary messenger gated channels
      • Eg:
        • Cyclic AMP (e.g., beta-adrenoceptors, alpha2- adrenoceptors, M2 muscarinic AChR)
        • Inositol 1,4,5-triphosphate (e.g., alphal- adrenoceptors, Ml/M3 muscarinic ACIIR).
