Plаce the events оf G prоtein аctivаtiоn in the correct order: Conformational change in the Gα subunit causes the release of GDP. GTP binds to the G protein. The activated receptor increases its affinity for the G protein. Ligand binding changes the conformation of the receptor’s cytoplasmic loops. A hormone or neurotransmitter binds to a G-protein-coupled receptor. The G protein binds to the activated receptor, forming a receptor-G protein complex.
