Multiple choice

The activated stimulatory G-protein’s subunit in a cAMP signaling cascade is

  2. the G-beta subunit

  3. the Gama subunit

  4. the Gama, beta subunit

  5. the alpha beta subunit

A Correct answer
Explanation

This is the correct option because the binding of the ligand to the receptor promotes the exchange of GDP for GTP and once the GTP binds to the G-proteins, the G-beta and Gama subunits dissociates and then G-alpha subunit becomes the activated stimulatory G-protein’s subunit.
