Verified step by step guidance

Understand the role of emulsification in digestion: Emulsification is the process of breaking down large fat globules into smaller, uniformly distributed particles. This increases the surface area for enzymes to act on, facilitating digestion.
Identify the compounds listed: Pepsin, bile salts, amylase, and lipase. Each has a specific function in digestion.
Pepsin is an enzyme that breaks down proteins in the stomach, not involved in fat emulsification.
Amylase is an enzyme that breaks down carbohydrates, primarily starches, and is not involved in fat emulsification.
Lipase is an enzyme that breaks down fats into fatty acids and glycerol, but it requires emulsified fats to work effectively. Bile salts are the compounds that emulsify fats in the small intestine, making them accessible to lipase.
