The graph illustrates the activity rate of enzyme X at a range of pH values. All other conditions are held constant. Using the data presented in the graph, which statement is correct?
- AEnzyme X is denatured in weak acid and alkali conditions.
- BThe kinetic energy of the substrate increases between $\text{pH }6$ and $8$.
- CThe kinetic energy of enzyme X is lowest at $\text{pH }4$.
- DThe frequency of effective collisions between the enzyme and substrate is greatest at $\text{pH }8$.
