Question

This table suggests that: A. a pH of 9 is the optimal pH for all enzymatic reactions. B. enzymes have particular pH's at which they function best. C. reactions proceed at the same rate for all enzymes. D. as the pH increases, the reaction rate always increases.

Answer 1

The answer to this question is B. enzyme have particular pH's at which they function best, since we can see both enzymes at different pH values, have different reactions rates: considering enzyme 1, the highest reaction rate is in pH 10, and considering the enzyme 2, the highest reaction rate is in pH 9.
