Endogenous Agonists Such as Adenosine and Prostacyclin,as Well As $\beta$ ₂-Adrenergic Receptor Agonists,can Elevate CAMP Concentration in Smooth Muscle

question 5

Multiple Choice

Endogenous agonists such as adenosine and prostacyclin,as well as $\beta$ ₂-adrenergic receptor agonists,can elevate cAMP concentration in smooth muscle.The elevation of cAMP in the smooth muscle results in activation of cAMP-dependent signaling pathways in the smooth muscle.This activation typically:

• A)Promotes relaxation,partly because of activation of myosin phosphatase.
• B)Promotes contraction,partly because of activation of potassium channels.
• C)Promotes relaxation,partly because of activation of Rho kinase.
• D)Promotes contraction,partly because of inhibition of InsP3 production.
• E)Promotes relaxation,partly because of inhibition potassium channels.
