QUESTION 50 In a signal transduction pathway involving a G protein-coupled receptor, the receptor first binds the ligand and activates a G protein. After the GTP- bound subunit of the G protein separates from the rest of the G protein, it travels until it encounters O a. the first messenger. O b. a receptor. O c. an effector protein. O d. a protein kinase. O e. another G protein
