Which of the following statements correctly describes the process of GPCR signaling? The GPCR activation is reversible after the signal of the ligand diminishes.
O The membrane-embedded enzyme uses GTP as a secondary messenger to initiate gene expression.
O The ligand attaches to both the GPCR and the membrane-embedded enzyme to activate the GPCR pathway.
O The ligand-bound GPCR sends a GTP molecule to an enzyme in the membrane and switches it into an active
state.

B) The membrane-embedded enzyme uses GTP as a secondary messenger to initiate gene expression.

Explanation:

Due to the fact G Protein Coupled Receptors (GPCRs) perceive many extracellular signals and transduce them to heterotrimeric G proteins, which further transduce these signals intracellular to appropriate downstream effectors and thereby play an important role in various signaling pathways

If im wrong so be it >:)

the answer is c. it will give up it's valence electron to the other atom.
