Use the diagram and scenario to answer the constructed response question. Marcus recently visited his doctor with complaints of
nausea, stomach cramps, bloating, and gas that occur approximately 45 minutes after eating ice cream, cheese, or drinking milk. The doctor’s report indicated that Marcus has an increased production of acidic toxins causing him to have an imbalanced intestinal pH. The doctor concluded he is lactose intolerant.

You must use the terms lactose, lactase, glucose and galactose in your response. (Hint: Use the picture to explain the process.)
