Question

QUESTION 8 Which statement about protein digestion and absoption is INCORRECT? ? In the small inteste, membrane bound enterokinase activates chymotypsinogen and the resulting chymotrypsin then converts trypsionogen into its activated form chymotrypsin. ? Many enzymes that are involved in the digestion of polypeptides are secreted by the pancreas into the small intestine in their zymogen forms. ? The low pH of the stomach activates pepsinogen into pepsin by causing a conformational change that leads to the removal of an inhibitory domain from the active site. ? Single amino acids are absorbed across the intestinal epithelial cell (i.e. from the intestine into the blood) using a similar transport system as glucose.
