Question

In the presence of lactase, lactose breaks down into molecules of

• A. Glucose and galactose
• B. Glucose and fructose
• C. Galactose only
• D. Glucose only

Answer 1

The correct option is A Glucose and galactose

Lactase is primarily a digestive enzyme that is produced by specialized cells that line the lumen of the small intestine.

Lactase primary function is to break down a type of sugar called as lactose. Lactose is a sugar found in milk and other dairy products. As a large sugar compound, lactose cannot be absorbed naturally by your body. In order to metabolize this form of sugar, your body needs lactase to break down lactose into two smaller particles called as glucose and galactose. These smaller sugar molecules are more easily absorbed by the cells in your intestine. Without lactase, lactose remains in your digestive tract and cannot be used by your body.
