Question

Quizplus · Accepted Answer

A person with lactose intolerance cannot break down lactose, as they lack the enzyme lactase, which is responsible for breaking down lactose into simpler sugars. When lactose stays undigested in the intestines, it becomes food for bacteria present in the gut. These bacteria break down lactose, producing various gases, including carbon dioxide gas, which causes abdominal cramps and discomfort.
