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. Now, fructose, on the other hand, doesn't actually use this same system. It doesn't use ATP and it enters the cell via a different type of integral protein that basically allows for passive transport. So not using any ATP molecule, but when fructose is inside, the majority of fructose is transformed into glucose.
