Q122 on p. 126 of EK Biology Which of the following is the best explanation for why pancreatic enzymes are secreted in zymogen form? A. A delay in digestion is required in order for bile to increase the surface area chyme C. Zymogens will not digest bile in the pancreatic duct D. Pancreatic cells are not as easily replaced as intestinal epithelium I picked C. Correct answer is D because "only D is both true and reveals a benefit for enzymes to be inactive while in the pancreas." "C is true but not an adequate explanation". I don't get it, can someone explain why its D. So what if pancreatic cells are NOT as easily replaced as intestinal epithelium?!
