Bile produced in the liver is associated with which of the following?

(1) Emulsification of fats into tiny globules (micelles) in the small intestine by bile salts

(2) Digestive action of pancreatic amylase

(3) Emulsification of fats into tiny globules in the stomach

(4) Digestion of proteins into amino acids

Bile aids in digestion and absorption of fats because it contains:
