Final answer:
Contrary to the notion, pancreatic enzymes are not necessary for vitamin B12 absorption; instead, it is the intrinsic factor from the stomach that facilitates its absorption in the small intestine.
Step-by-step explanation:
Pancreatic enzymes are not necessary for the absorption of vitamin B12. It is the intrinsic factor, which is secreted by the stomach, not the pancreas, that is required for vitamin B12 absorption in the small intestine. Therefore, the statement 'Pancreatic enzymes are necessary for absorption of vitamin B12' is false.
The role of pancreatic enzymes is mainly in the breakdown of proteins, carbohydrates, and fats within the small intestine. For example, trypsin is a pancreatic protease that breaks down proteins. While these enzymes play a crucial role in the digestion and subsequent absorption of many nutrients, the absorption of vitamin B12 specifically depends on the intrinsic factor from the stomach for successful absorption in the small intestine.
