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. And so, because the PKA phosphorylates and deactivates the sodium hydrogen antiportic system, this basically inhibits the ability of these intestinal cells to reabsorb that sodium back into the cell. And so what that means is there is a net flow of sodium outside of the cell and the cell loses sodium ions to the lumen of that small intestine. Now, number two, PKA also actually opens up chloride ion channels.
