Question

Suggest one reason why the level of blood glucose rises at all in lactose-intolerant people after the lactose tolerance test, when their only source of carbohydrate is lactose.

Answer 1

Answer:

Normally, when lactose reaches the digestive system, the lactase enzyme breaks it down into glucose and galactose. The liver then changes the galactose into glucose, which enters the bloodstream and raises the person's blood glucose level.
