19. Celiac disease is caused by a misdirected immune response to the protein gluten. The villi in the small intestine are damaged by the patient's own immune response. Enzyme supplements designed to digest gluten have proved to be ineffective. Hypothesize why these enzyme supplements would not be active in the stomach. 20. Individuals with cystic fibrosis are plagued by increased production of mucus. This excess mucus has a variety of effects on the body, including decreased production of pancreatic enzymes and blockage of the pancreatic ducts that secrete enzymes. Describe how impaired pancreatic enzyme secretion affects digestion.

Gluten is a mixture of proteins abundant in wheat, barley, and rye. Although these grains are staples in the Western diet, almost 1 percent of Americans have celiac disease- a disorder of the intestines caused by an abnormal immune response after eating gluten. This immune response damages the fingerlike villi of the small intestine, which can lead to intestinal upset and malnourishment. Currently, the only treatment is to maintain a strict gluten-free diet. Based on the experiment in question $15,$ propose how AN-PEP might be used to treat celiac disease.
Celiac disease is dangerous in affected individuals, because ingesting gluten damages the villi of the small intestines. Why is this potentially life threatening? a. The villi aid in mechanical digestion of food particles. When they are damaged, nutrients cannot be digested properly in the body. b. Villi increase the surface area of the small intestine, which aids in the absorption of bile salts. This nutrient cannot be absorbed when they are damaged. c. Villi decrease the surface area of the small intestine available for absorption. Nutrients cannot properly enter the bloodstream when they are damaged. d. Villi increase the surface area available for nutrient absorption. When villi are damaged, nutrients cannot properly enter the bloodstream.
