Q. Which one of the following statements is incorrect about enzyme catalysis?
A) Enzymes are least reactive at optimum temperature
B) Enzymes are mostly proteinous in nature
C) Enzyme action is specific
D) Enzymes are denaturated by ultraviolet rays and at high temperature
Explanation
[Solution from source] Enzymes show maximum (not least) activity at their optimum temperature, so that statement is incorrect. The other statements are true: most enzymes are proteins, their action is highly specific, and heat or UV radiation denatures them. Answer (1).
