geekymlethank you! it was the wording of the question which got me!!+12020-04-19T11:25:29Z
androI think there were two possible ways of approaching this.
The first was by appreciating that the tumor cells ( which release Growth Hormone ) would express growth hormone releasing hormone receptors GHRH receptors - GHRH uses the Gs signalling pathway ( Net effect an increase in cAMP from the increased activity of adenyl cyclase )
The second and more straight forward approach
From the stem of the question already they told us we are dealing with an overactivation of the G alpha stimulatory subunit .
If the GTPase aint working ( meaning it cant be inactivated ) , the effect would be an increase in the activity of adenyl cyclase+32020-04-21T10:18:34Z
