ORAL REHYDRATION THERAPY
1) REQUIRES BOTH NaCl AND GLUCOSE; NEITHER ALONE WORKS
THE Na+/ GLUCOSE SYMPORT PROTEIN MUST TRANSPORT Na+AND GLUCOSE TOGETHER
2) TRANSPORT OF NaCl AND GLUCOSE ACROSS THE INTESTINAL EPITHELIUM CAUSES OSMOTIC FLOW OF WATER FROM THE INTESTINAL LUMEN INTO THE BLOOD, LEADING TO REHYDRATION
