    Michaelis constant (km) of an enzyme is substrate concentration at which the reaction attains

    A)  its maximum velocity

    B)  half its maximum velocity

    C)  double its maximum velocity

    D)  its normal velocity

    Correct Answer: B

    Solution :

    : Michaelis constant\[({{K}_{m}})\]is the concentration of substrate that permits an enzyme reaction rate to be half-maximal, or at which half of the substrate molecules are engaged with enzyme molecules.
