Explain about G-protein

A. When an agonist binds to the binding site of a G-protein-coupled receptor (GPCR), this leads to GTP displacing a GDP bound to the alpha subunit of the G-protein.

B. When an antagonist binds to the binding site of a G-protein-coupled receptor (GPCR), this has no effect on the GDP that is bound to the alpha subunit of the G-protein.

C. When GTP binds to an alpha subunit of the G-protein, this leads to the alpha subunit of the G-protein dissociating from the beta and gamma subunits of the G-protein.
