    Each graph shows the rate of reaction of an uninhibited enzyme and that of the same enzyme in the presence of a constant amount of either a competitive or a non-competitive inhibitor. Which graph is correctly labelled?

    A)       

    B)

    C)       

    D)

    Correct Answer: D

    Solution :

    [d] With increasing substrate concentration in the presence of a competitive inhibitor, the rate of reaction only remains constant at a later stage. This is because the additional substrates can compete with the inhibitor for the enzyme's active site. Thus, graph [d] is correct.
