So once again, let's summarize what we just said. So in diagram one, we basically have these special proteolytic digestive enzymes found on the brush water of the anterocy on the apical side, on the apical membrane that break down our disaccharides into their individual monosaccharide form. Then what happens is on the basilateral side, we have specialized types of sodium, potassium, Atpas pumps that establish an electrochemical gradient by using ATP molecules. So we create a lower concentration of sodium inside the cell. Now, we have specialized types of cotransport or protein membrane protein molecules that are found on the apical side that allow the movement of sodium into the cell. At the same time, glucose and galactose also travels into the cell.
