what is the function of bile?
multiple choice
emulsify fats to assist in their chemical digestion
assist in the digestion of starches
denature proteins to assist in their absorption

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. This increases the surface area of fats. As a result, lipase (the enzyme that digests fats) can act more effectively on them, thus assisting in their chemical digestion. Starch digestion is mainly carried out by amylase enzymes (like salivary amylase and pancreatic amylase), not bile. Protein denaturation and digestion are related to enzymes like pepsin (in the stomach) and pancreatic proteases, not bile.

Answer:

Emulsify fats to assist in their chemical digestion
