  sub:_7 prov:value "Binding of an endogenous or exogenous agonist to beta 1-adrenergic receptors on the surface of cardiac myocytes causes G alpha proteins to activate adenylyl cyclase, which in turn catalyzes the conversion of ATP to cAMP. cAMP activates multiple protein kinases, including protein kinase A. PKA phosphorylates and activates sarcolemmal Ca2+ channels and thereby increases cardiac myocyte contractility." ;
