A)As the substrate concentration increases,the activity of the enzyme decreases.
B)As the substrate concentration increases,the effect of the inhibitor was overcome and enzyme activity was restored.
C)As the enzyme concentration increased,the effect of the inhibitor was overcome and enzyme activity was restored.
D)As the enzyme concentration increased,the effect of the inhibitor was more pronounced.
E)As the competitive inhibitor concentration decreased,the reaction rate also decreased.

Quizplus · Accepted Answer

The graph shows that when a competitive inhibitor is present, the reaction rate of the enzyme initially decreases as the substrate concentration increases. However, as the substrate concentration continues to increase, the effect of the inhibitor is overcome and the enzyme activity is restored. This is consistent with option B, where the effect of the inhibitor is overcome and enzyme activity is restored with increasing substrate concentration.
