ION CHANNELS/TRANSPORTERS

Ion channels help establish and control the small voltage gradient across the plasma membrane of cells by allowing the flow of ions down their electrochemical gradient. They are present in the membranes that surround all biological cells.

They are present on all membranes of cell (plasma membrane) and intracellular organelles (nucleus, mitochondria, endoplasmic reticulum, golgi apparatus and so on). Such "multi-subunit" assemblies usually involve a circular arrangement of identical or homologous proteins closely packed around a water-filled pore through the plane of the membrane or lipid bilayer. Some channels permit the passage of ions based solely on their charge of positive (cation) or negative (anion).
