Given that catalase has a kcat of 40,000,000 s⁻¹ and DNA polymerase I has a kcat of 15 s⁻¹, what can be inferred about their catalytic efficiencies?

• A. Catalase is much more catalytically efficient than DNA polymerase I.
• B. DNA polymerase I is more catalytically efficient than catalase.
• C. Both enzymes have the same catalytic efficiency.
• D. Catalase has a lower catalytic efficiency than DNA polymerase I.

Answer: (A)
