Multiple Choice

Which of the following statements about lipase is correct?

Lipase is a non-enzymatic protein found in the liver.

Lipase is an enzyme primarily found in the pancreas and is involved in the digestion of lipids.

Lipase is an enzyme found exclusively in the stomach and digests carbohydrates.

Lipase is an enzyme that catalyzes the breakdown of proteins in the small intestine.

Verified step by step guidance

Step 1: Begin by understanding the function of lipase. Lipase is an enzyme that catalyzes the hydrolysis of lipids (fats) into glycerol and free fatty acids. This is a key step in lipid digestion.

Step 2: Identify the primary location of lipase activity. Lipase is primarily secreted by the pancreas and acts in the small intestine, where it plays a crucial role in breaking down dietary fats.

Step 3: Eliminate incorrect statements based on the function and location of lipase. For example, lipase is not a non-enzymatic protein, nor is it involved in carbohydrate or protein digestion.

Step 4: Confirm that lipase is not found exclusively in the stomach. While some lipase activity occurs in the stomach (gastric lipase), the majority of lipase is secreted by the pancreas and functions in the small intestine.

Step 5: Conclude that the correct statement is: 'Lipase is an enzyme primarily found in the pancreas and is involved in the digestion of lipids.' This aligns with the biochemical role and location of lipase in the human body.
