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

Options

A. Enzymes are mostly proteinous in nature
B. Enzyme action is specific
C. Enzymes are denatured by ultraviolet rays and at high temperature
D. Enzymes are least reactive at optimum temperature.

Answer

D

Explanation

The rate of an enzyme reaction becomes maximum at a definite temperature, called the optimum temperature. On either side of the optimum temperature. The enzyme activety decreases. The optimum temperature range for enzymatic activity is `298-301K` . Human body temperature being `310K` is thus suited for enzyme-cataysed reactions.
