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

Options

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

Answer

D

Explanation

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