Question

Which of the following statements comparing enzymes and nonenzymatic catalysts are correct? (Select all that apply.) a. Biological catalysts are orders of magnitude more effective catalysts. b. The activity of both enzymes and nonenzymatic catalysts increases with increasing temperature. c. Enzymes are effective under mild conditions, whereas nonenzymatic catalysts require higher temperatures and pressures. d. All enzymes are catalysts, but not all catalysts are enzymes.

Answer 1

Enzymes are significantly more effective catalysts than nonenzymatic catalysts. They can catalyze reactions at higher rates and under mild conditions. All enzymes are catalysts, but not all catalysts are enzymes.

Step-by-step explanation:

The correct statements comparing enzymes and nonenzymatic catalysts are:

a. Biological catalysts are orders of magnitude more effective catalysts.

c. Enzymes are effective under mild conditions, whereas nonenzymatic catalysts require higher temperatures and pressures.

d. All enzymes are catalysts, but not all catalysts are enzymes.

Enzymes are biological catalysts that are significantly more effective than nonenzymatic catalysts. They can speed up reactions to a much greater extent. Enzymes are highly efficient and can catalyze millions of reactions per second. Additionally, enzymes are effective under mild conditions, while nonenzymatic catalysts require higher temperatures and pressures to be effective. Lastly, all enzymes are catalysts, but not all catalysts are enzymes.
