In cystic fibrosis, the enzymes most significantly affected are the pancreatic digestive enzymes, including lipase, protease, and amylase, as the thick mucus produced by the disease blocks their secretion from the pancreas into the small intestine. (1) Why did the enzyme stop working? (2) How will the lack of digestive enzymes in the small intestines affect the digestion rate and nutrient absorption rate?
