A) digestion of fat
B) digestion and absorption of fat
C) digestion of protein
D) digestion of protein and fat
Correct Answer: B
Solution :
Bile probably contains no digestive enzyme but contains inorganic salts. They nutrilize the HCl, imparting alkalinity to chyme and inactivating gastric pepsin. Here the fat is emulsify which facilitates easy action of lipases of pancreatic juice upon the fat. The bile salts also help in absorption of fatty acid, monoglycerides cholesterol and other lipids from chyme. The pancreatic juice contains protein-splilting enzymes (endopeptidases) ie, Trypsin of chymotrypsin. These enzymes split the proteose, peptones; large polypeptides and remaining proteins of chyme into smaller peptides of various sizes.
