Question

multiple choice question
an individual with lactose intolerance is lacking the enzyme:

amylase.
lactase.
maltase.
sucrase

Explanation:

Lactose intolerance occurs when the body lacks lactase, the enzyme needed to break down lactose (milk sugar). Amylase breaks down starch, maltase breaks down maltose, and sucrase breaks down sucrose—none are related to lactose digestion. So the correct enzyme is lactase.

Answer:

B. lactase (assuming the options are labeled A - D with B as lactase; if the original options had different labels, adjust accordingly, but based on the options, the correct one is the lactase option)
