Put the following events in epinephrine signaling through the beta-adrenergic receptor in order. activation of cellular responses leads to smooth muscle relaxation The G protein subunits dissociate from one another PKA catalyzes the phosphorylation of proteinsAdenylate Cyclase catalyzes the conversion of ATP to cAMP Epinephrine binds to a p-adrenergic receptor on a smooth muscle cell cAMP activates protein Kinase A Binding causes a conformational change in the receptor The a subunit activates Adenylate Cyclase
