What enzyme speeds up the breakdown of fats in food? pepsin lipase protease insulin

The answer is lipase.

Lipase is a kind of enzyme produced by the pancreas, and used in the duodenum. It helps speed up the breakdown of fat and lipids into 3 fatty acid molecules and 1 glycerol molecule.

In addition, to help the breakdown of fat, bile is also produced by the liver. Bile can help turn fat into numerous oil droplets, so that the surface area of fat can be increased and can be broken down by enzyme lipase later on in a faster rate.

Meanwhile, Pepsin and protease are the enzymes which can speed up the breakdown of protein from protein to small polypeptides and to amino acids respectively, and insulin can help control the blood glucose level.
