Step 1
What is the pH when enzyme activity is highest?
Answer
To determine the pH at which enzyme activity is highest, we refer to the given graph. The peak of the curve indicates the optimal pH for enzyme activity. Observing the graph, the highest point of enzyme activity occurs around pH 10. Therefore, the answer is:
C pH10.
