Question

How would the digestion of proteins and carbohydrates be affected if there is and blockade in the bile duct?

Answer 1

Explanation:

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.

Answer 2

Answer:

• Bile will be produced by the liver but will not go to the duodenum of the small intestine if the bile duct is obstructed.
• Large fat globules are broken down into smaller globules during the emulsification of fats, which is accomplished by bile.
• Small fat globules are not formed from dietary fats because the entry of bile is prevented.
• Because of this, lipase does not function properly, preventing lipid from being absorbed.
• The pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase finish protein digestion in the small intestine.
• These enzymes won't be secreted and proteins won't be completely digested if the pancreatic duct is blocked.
• The pancreatic enzyme pancreatic amylase aids in the breakdown of starch into its component disaccharides.
• As well as secreting these enzymes, the pancreas also produces lactase, sucrase, and maltase, which converts disaccharides into monosaccharides.
• Therefore, by limiting the breakdown of carbohydrates into monosaccharides, blockage of the pancreatic duct will also interfere with the digestion of carbohydrates.
