Question

Lily visits her family doctor because she experiences an upset stomach after drinking milk. The doctor tells her that this symptom is caused by a lack of the enzyme lactase. Lactase breaks down lactose, the sugar in milk which is made of several parts. What does lactose break down into?

Answer 1

Lactase breaks lactose down into simpler sugar forms called glucose and galactose. These simple sugars are then easily absorbed into the bloodstream and turned into energy — fuel for our bodies.
