DeKwami is conducting an experiment in which he needs to use both sucrase and catalase. Which pH should he prepare to ensure that BOTH of the enzymes will show some activity?

pH of 6.5

Explanation:

The pH favorable to an enzyme where it is most active is called optimum pH. The optimum pH of sucrase is about 6.0 while that of catalase is 7.0.  Both enzymes can however still show some activity when the solution is slightly basic or slightly acidic (from it's optimum pH). Hence, getting the middle point (6+7/2 = 6.5) between the optimum pH of the two enzymes and preparing same will ensure the enzymes show some activity.
