Stimulation of β-adrenoreceptor, a G-protein-linked receptor involves generation of secondary messenger/s known as

Beta-adrenergic receptors couple to the Gs protein. When activated, Gs stimulates adenylyl cyclase, which converts ATP into cyclic AMP. This cAMP acts as the second messenger that activates protein kinase A (PKA) and triggers the downstream responses of the sympathetic system. IP3 and DAG come from a different pathway (phospholipase C via Gq) and are not produced in this beta-adrenoceptor signaling. So the secondary messenger generated here is cAMP.
