Question

Quizplus · Accepted Answer

D₁ dopamine receptors inhibit adenylyl cyclase, which decreases the synthesis of cAMP, whereas D₂ dopamine receptors stimulate adenylyl cyclase, which increases the synthesis of cAMP. Therefore, their effects on adenylyl cyclase are opposite.

D1 and D2 Dopamine Receptor Subtypes Have _______ Effects on Adenylyl

D₁ and D₂ Dopamine Receptor Subtypes Have _______ Effects on Adenylyl
