Regarding molecular switches, which of the following is TRUE? A GTP-binding protein exchanges its bound GTP for GDP to become activated. Ras is a monomeric G-protein that act as a molecular switch G-proteins are monomeric proteins that act as molecular switches Phosphatases remove the phosphate from GTP on GTP-binding proteins, turning them off. Protein kinases transfer the terminal phosphate from GTP onto serine, threonine or tyrosine residues in a protein.

Which of the following statements about G-protein signaling pathways are true? Choose one or more: A. The Gα subunit activates by exchanging GDP for GTP. B. The activated receptor causes the Gα and Gβγ subunits to non-covalently bind to one another. C. When activated, both the Gα and the Gβγ subunits can modulate target proteins. D. The ligand must bind to the G-protein-coupled receptor in order for the G protein to be activated. E. GPCRs are transmembrane proteins, whereas their heterotrimeric G proteins are peripheral membrane proteins.
