Question

Based on this graph, it appears that carboxylesterase is most active at a pH of

A. 3.5
B. 1.5
C. 5
D. 4
 
The image is a graph that illustrates the activity of the enzyme carboxylesterase in relation to pH levels. - **Title:** Carboxylesterase - **X-axis:** Represents pH, ranging from 0 to 7. - **Y-axis:** Indicates enzyme activity. ### Graph Description: - The enzyme activity is depicted as a red curve. - The graph shows a peak in enzyme activity at a pH around 2, indicating this is the optimal pH for carboxylesterase activity. - There is a sharp increase in activity as the pH approaches 2 from the left, followed by a gradual decline in activity as the pH increases beyond 2. - The enzyme activity significantly decreases as the pH reaches 4 and above, indicating reduced functionality in more neutral or alkaline environments. This graph effectively demonstrates that carboxylesterase functions best in acidic conditions.
