If there is a Gs alfa subunit gain-of-function mutation, this results in:: (A) Decreased cAMP, (B) Decreased IP3, (C) Increased GTPase activity, (D) Increased cAMP
Answer is D. D i.e. Increased cAMPGs-a subunit gain would cause increased adenyl cyclase level - ultimately resulting in increased c-AMP levelQ, (because adenyl cyclase conves ATP to c-AMP).
