Polyethylene glycol (PEG) is a solute that is consumed in order to "clean out" the digestive tract in preparation for a colonoscopy. PEG cannot enter intestinal cells as there is no transport mechanism for it. How would this affect the absorption of water into the small intestine? (assume that it is taken at the correct dose and you are not actually reversing the concentration gradient across the intestinal cells.) Explain your answer in terms of concentration gradients.
