Receptor (biochemistry) - Wikipedia
WEBIn biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems. [1] These signals are typically chemical messengers [nb 1] which bind to a receptor and produce physiological responses such as change in the electrical activity of a cell.
