Answer:

the beta-gamma subunit to form an inactive trimeric protein.

Explanation:

When inactive, the alpha subunit of the G-protein is bound to a GDP molecule.

  • The guanine nucleotide-binding proteins (commonly called G proteins or GTPases) represent an evolutionarily conserved protein family that serves to switch on/off different signaling pathways within the cell.

  • G-proteins are composed of three different subunits: Gα, Gβ, and Gγ subunits.

  • When GDP is bound to , this subunit remains bound to the Gβ subunit in order to form an inactive heterotrimeric protein.

  • When GTP is bound to the G-protein, then Gα dissociates from the other subunits and triggers the activation of the G-protein.

In conclusion, when inactive, the alpha subunit of the G-protein is bound to a GDP molecule.
