Lactase is an enzyme that is produced in the lining of the intestines. This enzyme helps the body speed up the breakdown of carbohydrates that are found in dairy products, such as milk, yogurt, and cheese.

Answer

β-galactosidase enzyme that is involved in the hydrolysis of the disaccharide lactose into constituent galactose and glucose monomers.

Regulation of cell processes

Explanation:

Lactase is an enzyme that helps in the breaking down of disaccharide sugar, lactose, found in many foods. It does it by converting the lactose into its component reducing sugars - glucose and galactose. This enzyme is produced by some special cells lining the intestinal walls of humans and forms a kind of chemical barrier known as brush border where foods must pass through before being absorbed. By so doing, foods are screened for the presence of lactose and any lactose is broken down before the foods are given a pass.
