Explanation: The liver produces bile. Bile emulsifies fats, It breaks up large droplets of fats into smaller droplets, thereby increasing the surface area for lipases to work on, speeding up the digestion of fat by the lipase. Bile further neutralizes the acid produced by the stomach to provide an alkaline environment for enzymes in the small intestine.
Bile acids are important for digestion and absorption of fats and fat-soluble vitamins in the small intestine.
