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.
