Question

multiple choice question
what is the function of bile salts?
o blocks absorption of fatty acids, cholesterol, and the fat - soluble vitamins a, d, e, and k
o mixes fatty substances with proteins for better absorption
o increases surface area of fatty substances, allowing better access for lipase enzymes

Explanation:

Bile salts emulsify fats. Emulsification breaks large fat globules into smaller droplets. This increases the surface area of fatty substances. Lipase enzymes can then act more effectively on these smaller droplets.

• The first option is incorrect as bile salts aid in absorption, not block it.
• The second option is wrong as bile salts do not mix fatty substances with proteins for absorption.

Answer:

increases surface area of fatty substances, allowing better access for lipase enzymes
