Which statement correctly describes fat digestion?

• A. Fats require gastric lipase, bile, and pancreatic lipase
• B. Fats are digested only by salivary lipase
• C. Fats do not require bile
• D. Fats require only pancreatic lipase

Answer: (A)

Fat digestion relies on both emulsification and enzymatic breakdown. Bile salts in the small intestine emulsify fats, turning large droplets into smaller ones so enzymes can work more effectively. Pancreatic lipase is the main enzyme that digests these emulsified fats into absorbable products like monoglycerides and fatty acids. The stomach provides some initial fat digestion through gastric lipase, which helps, especially with certain fats, but its contribution is smaller compared to pancreatic lipase in adults. Salivary lipase in the mouth plays only a limited role and doesn’t complete fat digestion. So fat digestion truly involves gastric lipase, bile, and pancreatic lipase working in concert, making that statement the best description.
