    Km value of an enzyme is substrate concentration at

    A)  \[\frac{1}{4}\,{{V}_{\max }}\]

    B)  \[2\,{{V}_{\max }}\]

    C)  \[\frac{1}{2}\,{{V}_{\max }}\]

    D)  \[{{V}_{\max }}\]

    Correct Answer: C

    Solution :

    The Michaelis constant \[({{K}_{m}})\] is the concentration of substrate at which the enzyme gives an observed reaction rate that is one-half \[{{V}_{\max }}\].
