Question

Short / Long answer type questions.
How would it affect the digestion of proteins and carbohydrates in the duodenum of a man if there is a blockade in the pancreatic duct? Explain.

Answer 1

Digestion of protein is completed in the small intestine by the pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase. If there is a blockade of the pancreatic duct these enzymes will not be secreted and complete digestion of proteins will not occur. Enzyme pancreatic amylase from the pancreas helps in the digestion of starch, it breaks the polysaccharide down into disaccharides. The pancreas also secretes enzymes lactase, sucrase and maltase, which break down the disaccharides into monosaccharides. So, blockade of the pancreatic duct will also cause disruption of the digestion of carbohydrates by preventing their breakdown into monosaccharides.
