So let's move on to the second type of protein known as the potassium, the sodium chloride cotransport, a protein. This is this protein here. So this protein actually functions as a result of the Atpas pump, because the Atpas pump is able to establish this electrochemical gradient in which we have more sodium. On the lumen side, this NaCl co transporter protein allows the movement of sodium down its electrochemical gradient from the lumen side to the inside of the cell. At the same time, it also moves the chloride along with the sodium. So we see that we have the reabsorption of chloride and sodium taking place, and we basically move these ions into the interstitial, the surrounding tissue of our distal convolute tubule.
