[{'content': 'Which of the following is the most impoant effector pathway for action of Nitric Oxide: \nSelect and explain. \nA. Adenylate cyclase pathway, B. Phosphatidylinositol pathway, C. Guanylate cyclase pathway, D. MAP Kinase pathway', 'role': 'user'}, {'content': 'Answer: C \nExplanation: The most impoant effector pathway for NO is activation of the soluble form of guanylyl cyclase. Soluble guanylate cyclase (sGC) catalyses the conversion of guanosine 5&;-triphosphate (GTP) to cyclic guanosine 3&;5&;-monophosphate (cGMP) Ref: Harper', 'role': 'assistant'}]
