Question

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

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

Answer 1

The correct option is B Enzymes are least reactive at optimum temperature

Enzymes are most reactive at optimum temperature. The physiological temperature (${37}^{o}C$) is the optimum temperature for most enzymes.
