Question

List two roles of bile juice.

Answer 1

1. Emulsification of Fats: Bile salts help emulsify fats. Emulsification reduces fat globules to tiny droplets, allowing digestive enzymes such as lipase to function more efficiently. This mechanism helps digest and absorb fats in the small intestine.
2. Neutralisation of Otyme: Bile, an alkaline substance, neutralizes the acidic chyme produced by the stomach when released into the small intestine. The pH adjustment creates an optimum environment for pancreatic enzymes to digest carbs, proteins, and lipids in the small intestine.
