Question

Use the graph to answer this question.

This enzyme _______ (does, does not) appear to have a significant level of activity at a pH of 5.

### Carboxylesterase Enzyme Activity

The graph illustrates the enzyme activity of carboxylesterase across a range of pH levels from 0 to 7. 

- **X-axis (Horizontal):** Displays the pH levels, ranging from 0 to 7.
- **Y-axis (Vertical):** Represents enzyme activity. The specific units of measurement for enzyme activity are not provided.
- **Curve Description:** The red curve shows that enzyme activity increases sharply, peaking around a pH of 2. After reaching its peak, the activity declines steadily as the pH level continues to rise, with a significant drop beyond pH 3. 

### Interpretation
- **Optimal pH:** Carboxylesterase exhibits its highest activity at approximately pH 2, indicating this is its optimal pH for catalytic function.
- **Activity Decline:** Beyond the optimal pH, the enzyme's activity decreases sharply, suggesting reduced efficiency in more neutral or basic environments.

This graphical representation highlights the sensitivity of carboxylesterase activity to pH changes, emphasizing the importance of pH in enzymatic functions.
