Question

at what ph are both enzymes working? enzyme activity

Explanation:

Step1: Observe the graph

We have a graph showing enzyme - activity vs pH for two enzymes (A and B). We need to find the pH values where both enzymes have non - zero activity.

Step2: Identify overlapping activity regions

By looking at the graph, we see that the two curves (representing the two enzymes) overlap in the pH range of 6 - 8.

Answer:

pH values between 6 and 8
