Which one of the following statements is incorrect about enzyme catalysis?

Options

  1. AEnzymes are mostly proteinous in nature
  2. BEnzyme action is specific
  3. CEnzymes are denaturated by ultraviolet rays and at high temperature
  4. DEnzymes are least reactive at optimum temperature

Correct answer

D. Enzymes are least reactive at optimum temperature

Step-by-step solution

Most of the enzymes have proteinous nature. They are highly specific and get denaturated by high temperature or UV rays. At optimum temperature, which is generally in between 25^ -35^ C , enzyme activity is maximum.
