Question

Bile salts ___________ fats in duodenum.

• A. Assimilate
• B. Absorb
• C. Emulsify
• D. Regurgitate

Hint:

Bile salts aid fat digestion by emulsification, not by enzymatic breakdown.

Answer 1

The Correct Option is C

Step 1: Understanding the role of bile salts.
Bile salts are secreted by the liver and released into the duodenum through bile. They do not digest fats chemically but help in their physical breakdown.
Step 2: Process of emulsification.
Emulsification is the process by which large fat globules are broken into smaller droplets. This increases the surface area of fats, making them more accessible to the action of lipase enzymes.
Step 3: Analysis of options.
(A) Assimilate: Refers to utilization of nutrients by body cells, not a digestive action in the duodenum.
(B) Absorb: Absorption of fats occurs mainly in the intestine via lacteals, not by bile salts.
(C) Emulsify: Correct, as bile salts break fats into small droplets in the duodenum.
(D) Regurgitate: Unrelated to digestion of fats.
Step 4: Conclusion.
Bile salts emulsify fats in the duodenum to aid efficient digestion.
