Question

Emulsification of fats occurs by
A. Bile salts
B. Bile pigments
C. Pancreatic juice
D. Succusentericus

Answer 1

Hint: The process of emulsification of fats takes place in the liver which aids in the process of the digestion, they are converted into smaller globules by the secretions of the liver.

Complete answer:
The digestion of food is required to break the complex particles into smaller and simplified one so that these particles can be easily utilized and absorbed by the body.
The emulsification of fats takes place in the liver in which the larger fat molecules are converted into smaller fat globules. These salts are secreted in the liver and then stored in the gallbladder. They are then further released in the small intestine where the emulsification takes place. Then the further process of digestion of the smaller fat globule takes place by the fat digesting enzyme called lipase, secreted by pancreas in the pancreatic juice. Bile released by the liver also activates the lipase enzyme which is responsible for further digestion.In the emulsification process, the surface area of the molecules is increased to increase the efficiency of the digestion process.
After complete digestion of fats, they get converted into fatty acids and glycerol, but these are not directly absorbed into blood as they are insoluble. These are firstly incorporated into droplets of small size called micelles. These are then converted into protein coated small fat globules and are known as chylomicrons and these are then transported to lymph vessels which finally releases them into the blood.

So, the correct answer is (A).

Note: Only fat molecules are emulsified by the bile salts, no other food component is broken and for each component like carbohydrate, proteins or fats to be broken down, specific enzymes are produced in the body.
