A hormone signals through a G protein-coupled receptor as shown in the diagram. After the production of IP3, which of these events will MOST quickly stop the transduction of the signal?A. the hydrolysis of IP3B. the hydrolysis of GTPC. the hydrolysis of PIP2D. the hydrolysis of the hormone I believe the answer is (B) the hydrolysisof GTP, because the G protein becomes inactive after GTP is hydrolyzed to GDP. However, the solution provided by Bartleby is (C). Please explain. Thanks
