WebLigand-gated ion channels are transmembrane ion channels that open or close in response to the binding of a chemical messenger like a ligand. Like we mentioned, a very common place to find ligand-gated ion channels are in electrically excitable cells like neurons. The reason why is because these ion channels react really quickly to the binding ... WebDec 30, 2015 · Cooperative binding is one of the most interesting and not fully understood phenomena involved in control and regulation of biological processes.
