What is the major mechanism of action of NO?

Question

Quizplus · Accepted Answer

The major mechanism of action of NO is the stimulation of guanylyl cyclase, which converts GTP to cGMP. This leads to the activation of protein kinase G, resulting in various physiological responses, such as relaxation of smooth muscle, inhibition of platelet aggregation, and vasodilation. ATP to cAMP, binding to intracellular receptors, phosphoinositol phosphate to DAG, and the Ras cascade are not mechanisms of action of NO.
