Question

a. at what ph does enzyme a work best at?
b. at what ph does enzyme b work best at?
c. how high was the enzyme efficiency for enzyme a at a ph of 8?
d. which enzyme works best at a basic ph?
e. which enzyme is the most efficient at any ph?

Explanation:

Step1: Find the peak for Enzyme A

From the table, Enzyme A has the highest efficiency value of 90 at pH = 4.

Step2: Find the peak for Enzyme B

From the graph, Enzyme B has its highest point around pH = 9.

Step3: Read Enzyme A efficiency at pH = 8

From the table, at pH = 8, Enzyme A efficiency is 35.

Step4: Identify enzyme for basic pH

Basic pH is above 7. Enzyme B has its peak in the basic range around pH = 9.

Step5: Compare overall efficiencies

Enzyme A has a maximum efficiency of 90, and by comparing with Enzyme B's graph - like behavior, Enzyme A is the most efficient at any pH.

Answer:

a. 4
b. 9
c. 35
d. Enzyme B
e. Enzyme A
