Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the function of bile?
A
to provide enzymes for fat digestion
B
to increase the surface area of fats for digestion
C
to emulsify starch
D
to acidify food entering the duodenum
Explanation: 

Detailed explanation-1: -Bile salts help in the emulsification of the fats i.e. breaking down of the fat into very small micelles so as to increase the surface area for the lipase to act and thus aiding in the digestion of fat.

Detailed explanation-2: -The liver releases bile, which contains lecithin, bile salts, and emulsifiers that help further break down fats. Bile grabs onto the fats, and the emulsifiers increase their surface area, making them easier for digestive enzymes to act on. Following this, enzymes break apart fatty acids.

Detailed explanation-3: -Through the process of emulsification, bile acids break down large lipid droplets into smaller ones, increasing the surface area for digestive enzymes.
