NettetWhen a hormone binds to the receptor, the G-protein is activated by binding guanosine triphosphate, or GTP, in place of GDP. After binding, GTP is hydrolysed by the G-protein into GDP and becomes inactive. The activated G-protein in turn activates a membrane-bound enzyme called adenylyl cyclase.
