Which of the following is false when comparing G proteins to small Ras GTPase proteins? Group of answer choices a. Both need GDP-GTP exchange to switch on/off of their activity. b. G-proteins are trimeric, but Ras proteins are monomeric. c. The activation of G proteins is required for G-protein-linked receptors, whereas the activation of Ras proteins depends on enzyme-linked receptors. d. Both use transmembrane domain to associate cell membrane.

Which of the following is TRUE about G protein-coupled receptors? Select one: a. G protein is attached to the cytoplasmic side of the plasma membrane b. Guanosine diphosphate (GDP) switches off the G protein c. Binding of the ligands to the receptors activates the kinase enzyme d. cAMP is required as a second messenger to elicit a cellular response e. Binding of the ligands to the adenylyl cyclase enzyme switches on the G protein

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