- A Neutralizing the acidity of fats entering the duodenum under typical physiological conditions
- B Emulsifying large fat globules into smaller droplets, increasing surface area for lipase action
- C Activating pepsinogen in the stomach before fats reach the duodenum in most observed cases
- D Directly hydrolyzing triglycerides into fatty acids and glycerol under most conditions studied
Correct answer: B. Emulsifying large fat globules into smaller droplets, increasing surface area for lipase action
Explanation: Bile salts emulsify fats, breaking large globules into smaller droplets and increasing the surface area available for pancreatic lipase to act on.
