Enzyme A and Enzyme B both catalyze the same reaction. If Enzyme A has a larger turnover number than Enzyme B, then which enzyme, if either, has a higher catalytic efficiency?

Enzyme B is more efficient because it's turnover number is smaller.
Enzyme A is more efficient because it's turnover number is larger.
Not enough information is provided to know for certain.

Answer:

Enzyme A, if we assume the concentration of the enzymes (A and B) are the same

Explanation:

As Enzyme turnover number is defined as the number of chemical conversions of substrate per second that a single enzyme can perform in its catalytic site, for a given enzyme concentration, we can say that the Enzyme A has a higher catalytic efficiency. This is true only if [Enzyme A] = [Enzyme B]
