Quizplus · Accepted Answer

Activation of adenylyl cyclase by the G_s protein causes an increased synthesis of the second messenger,cyclic adenosine 3',5'-monophosphate (cAMP).An increase in cAMP may lead to smooth muscle relaxation by increasing the inactivation of myosin light chain kinase,an enzyme initiating myosin-actin interaction and subsequent smooth muscle contraction.An increase in cAMP also leads to a decrease in intracellular calcium.ATP is used for cellular energy production.
