Question
Adenylyl cyclase converts
Explanation
Adenylyl cyclase catalyzes the conversion of ATP to the second messenger cyclic AMP. The enzyme is stimulated by GTP-bound Gαs and inhibited by GTP-bound Gαi. The resulting changes in cAMP concentration regulate protein kinase A and cyclic-nucleotide-gated channels, linking G-protein-coupled receptors to diverse physiological responses. Careful
