Multiple choice

Why does denaturation of an enzyme make it non-functional?

  1. Rearrangement of the amino acid sequence takes place.

  2. The 3D shape of the enzyme is disrupted.

  3. Peptide bonds break and amino acids are formed.

  4. New peptide bonds are formed.

B Correct answer
Explanation

The enzyme loses its function on denaturation because the 3D shape of the enzyme is disrupted. Due to disruption of shape, the active site is no more available.
