Potassium channel,molecular model. Side (lower centre) and end (upper right) views of the quaternary structure of a KcsA potassium ion channel. This membrane-spanning protein is composed of four identical subunits and allows the rapid movement of potassium (K+) ions across cell membranes. Potassium ion channels have many functions,including regulating the secretion of hormones,generating electrical nerve impulses,and controlling the pace of the heart | |
