Question

At a temperature below the freezing point, an enzyme is

• A. Unaffected
• B. Inactivated
• C. Slightly inactivated
• D. None of the above

Answer 1

The correct option is B Inactivated

Enzymes are basically proteinaceous in nature which catalyses biochemical reactions. It lowers the activation energy and leads to the conversion of substrate into product. At extreme temperatures, the enzymes denature and, hence gets inactive.

So, the correct answer is option B.
