Which statement(s) about lipases is/are true?
Digiron [165]

Answer:

The correct answer will be option- C.

Explanation:

Lipase is the enzymes which aid in the digestion of the fats in the body. The main types of digestive lipases are secreted by the pancreas which acts on the glycerol of the triglycerides.  The pancreatic lipase acts on the fats in the small intestine which break down the fats into smaller molecules called micelles.

Other type of lipases are present in the body which also helps in the digestion of the fats like lipoprotein lipase which acts on the lipoproteins formed by the breakdown of the cholesterol-like low and very low density lipoproteins. These lipoproteins in the blood are activated by the Apoc-II component and after the breakdown of lipoproteins delivers them to peripheral tissues.

Thus, Option-C is the correct answer.
