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

  • Enzymes are mostly proteinous in nature

  • Enzyme action is specific

  • Enzymes are denaturated by ultraviolet rays and at high temperature

  • Enzymes are least reactive at optimum temperature

Solution

D.

Enzymes are least reactive at optimum temperature

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 25-35o, enzyme activity is maximum.
