D Correct answer
Explanation

G-protein coupled receptors (GPCR) are responsible for signal transduction. GPCRs are linked to trimeric G proteins. G-proteins are GTPase switch proteins. These proteins are turned on or remained active when bound to GTP and turned off or inactivated when bound to GDP.
