Question

question 15 which describes the function of bile? breaking down proteins digest fats emulsifying fats producing bilirubin

Explanation:

Bile is produced by the liver and stored in the gallbladder. Its main function is to emulsify fats. Emulsification breaks large fat globules into smaller droplets, increasing the surface area for lipase (fat - digesting enzyme) action. Breaking down proteins is mainly done by proteases (e.g., pepsin, trypsin). While bile aids in fat digestion (indirectly by emulsifying), its direct function is emulsification. Bilirubin is a component of bile, not its function.

Answer:

Emulsifying fats
