Question

a person has a mutation in the enzyme that breaks down complex carbohydrates. that enzyme does not work anymore. what might be the result? this person can no longer produce glycogen. this person can no longer produce proteins. this person will be able to digest rice, but not meat. this person will be able to digest table sugar, but not rice.

Explanation:

The mutation affects the enzyme breaking down complex carbohydrates. Rice is a complex carbohydrate (starch), so it can't be digested. Table sugar is a simple sugar (sucrose), which doesn't require the same enzyme for breakdown. Other options are incorrect: glycogen production is unrelated to digestion of complex carbs, protein production isn't linked to this enzyme, and meat is protein/fat (not carbs, so digestion of meat isn't affected here).

Answer:

This person will be able to digest table sugar, but not rice.
