Question

Emulsification of fat is carried out by

(a) bile pigments

(b) bile salts

(c) HCI

(d) pancreatic juice.

Answer 1

Bile pigments (bilirubin and biliverdin) are the breakdown products of hemoglobin that are excreted in bile.
HCl in the stomach aids in protein digestion by activating inactive pepsinogen into active pepsin.
Pancreatic juice secreted by the pancreas is composed of different enzymes like trypsinogen, chymotrypsinogen, pancreatic lipase, carboxypeptidase, amylase, etc that help in the digestion of proteins, lipids, and carbohydrates.
Bile salts help in the digestion of lipids in the small intestine. They facilitate fat absorption by emulsifying fats.
So, the correct option is option B, bile salts.
