Question

Which is not true about inorganic catalysts and enzymes?

• A. They are specific.
• B. Inorganic catalysts require specific factors not needed by enzymes.
• C. They are sensitive to pH.
• D. They speed up the rate of chemical reaction.

Answer 1

Answer: (B)

Inorganic catalysts require specific factors not needed by enzymes.

Inorganic catalysts and enzymes both are specific as they required for the specific substrate. They speed up the reaction at specific pH and temperature so they are pH sensitive. But sometimes inorganic catalysts require specific factors which are not needed by enzymes .

So, the correct answer is B.
