Question

Quizplus · Accepted Answer

Disaccharidase enzymes are not secreted into the duodenal lumen; instead, they are located on the brush border membrane of the intestinal epithelial cells where they function to break down disaccharides into monosaccharides for absorption. Trypsinogen (a precursor to trypsin), bile salts, and gastric contents do enter the duodenal lumen as part of the digestive process.
