Final answer:
Lipase is an enzyme responsible for breaking down lipids (fats), not proteins, so the statement is false. The pancreatic lipase is particularly important for digesting lipids in the small intestine.
Step-by-step explanation:
The statement that lipase is a protein-digesting enzyme is False. Lipase is an enzyme that aids in the digestion of lipids (fats). Specifically, the enzyme lipase has various forms such as lingual lipase, which begins the digestion of lipids in the mouth, gastric lipase, which continues this process in the stomach, and pancreatic lipase, the most consequential form, which is responsible for the bulk of lipid digestion in the small intestine. Pancreatic lipase breaks down triglycerides into two free fatty acids and a monoglyceride. Therefore, the primary function of lipase is to break down fats, not proteins.
