What enzyme is responsible for digesting emulsified fats in the digestive system?
A
Trypsin
B
Amylase
C
Pepsin
D
Lipase
Verified step by step guidance1
Understand the role of enzymes in the digestive system: Enzymes are biological catalysts that speed up chemical reactions in the body, including the breakdown of food substances.
Identify the function of each enzyme listed: Trypsin is involved in protein digestion, amylase breaks down carbohydrates, and pepsin also digests proteins.
Recognize the process of fat digestion: Fats are first emulsified by bile salts in the small intestine, which increases the surface area for enzyme action.
Determine the enzyme responsible for fat digestion: Lipase is the enzyme that specifically breaks down emulsified fats into fatty acids and glycerol.
Conclude that lipase is the correct enzyme for digesting emulsified fats, as it acts on the emulsified fat droplets to facilitate absorption in the digestive system.
