Emulsification is Most Associated with Which Substance

Question

Emulsification is most associated with which substance?
A) Trypsin
B) Hydrochloric acid
C) Bile
D) Ptyalin

Accepted Answer

Emulsification is the process of breaking down large fat globules into smaller ones to increase their surface area. This process occurs in the small intestine with the help of bile, a substance produced by the liver and stored in the gallbladder. Bile contains bile salts that emulsify the fat, allowing lipase enzymes to more easily digest and absorb it. Trypsin and ptyalin are enzymes involved in protein digestion, while hydrochloric acid helps to break down food in the stomach.
