Answer:
Some G proteins activate adenylate cyclase, while others inhibit it.
Explanation:
G proteins helps in the signal transduction process that transfer message in the body. GPCRs (G-protein-coupled receptors) are located on the surface membrane of the cell.
The G protein can activates the protein or might deactivate the proteins that helps in the adenylate cyclase. The particular phosphorylation and dephosphorylation process at different sites by the G proteins can result in activation and inactivation of adenylate cyclase.
Thus, the correct answer is option (C).
