Best answer

Answer: 3. Denaturation makes the proteins more active.

Key idea: denaturation destroys the 3-D structure.

On denaturation (heat, acid), secondary and tertiary structures unfold, and the protein loses its biological activity. So the claim that denaturation makes proteins more active is wrong. The rest are correct.
