Question

Function of bile juice is:

• A. to catalyse chemical reaction.
• B. to emulsify the fats.
• C. absorption of fast soluble nutrients.
• D. converting proteins into simpler proteins.

Answer 1

The correct option is (B): ​

Explanation of the correct option:

1. The main function of the bile juice secreted from the liver is emulsification fats.
   
2. The bile is released in the duodenum ​where it emulsifies the dietary fats.
   
3. This emulsification helps with absorption of fats.
   

Explanation of the incorrect options:

Option (A):

1. ​Bile salt is not an enzyme and hence it does not act on the catalysis of the chemical components like the other chemicals.
   

Option (C):

1. It does not help with absorption of easily absorbable nutrients.

Option (D):

1. Proteases convert the complex proteins into simpler proteins and amino acids.
   
2. Pepsin and trypsin are the common proteases that act on the dietary proteins.
   

Final Answer: Function of bile juice is to emulsify the fats.
