Answer:
Denatured (unfolded) proteins do not function normally.
Explanation:
Proteins are the polymers made of the alpha amino acids that are linked through the peptide bond. Protein is one of the most important biomolecule acts as the main building block of the body.
Protein are specific in functions and works only when they have correct three dimensional structure. The denaturation of protein causes the change in its structure, makes the protein less folded and the protein is unable to perform its function after the denaturation.
Thus, the correct answer is option (2).
