And so this structure will not be able to turn itself off and that traps it in its active state. And so if we move on to this region here, we see that the Galpha protein will be trapped in the active state, which implies that it will continually stimulate the cyclic Amp production, which in turn stimulates the activity of the protein kinase A. And protein kinase A does two important things. Number one is protein kinase A actually phosphorylates the sodium hydrogen antiporters. So exchanges. And remember, antiporters are these pumps, membrane pumps that essentially utilize the gradient of one molecule to actually move another molecule against its gradient.
