C

The nurse administers epinephrine intravenously to a client diagnosed with heart block. In what order would the nurse predict the steps of signal transduction and intracellular events that occur when the beta-adrenergic receptors are stimulated? Drag the statements into the proper order. A) Epinephrineñbeta receptor complex activates G protein, which reacts with guanosine triphosphate. B) Increases in cyclic adenosine monophosphate (cMP) occurs. C) Epinephrine, the first messenger, binds to the beta receptor and initiates intercellular activity. D) Activated G protein then activates enzyme adenyl cyclase. E) cAMP is the second messenger beginning intracellular activities including an increase in atrioventricular conduction.
