    \[{{K}_{m}}\]is

    A)  product           

    B)  enzyme

    C)  constant          

    D)  unit

    Correct Answer: C

    Solution :

     Michaelis-Menten kinetics is one of the best known and simplest models of enzyme  kinetics.  \[{{K}_{m}}\]acts  as  a Michaelis-Menten   constant   in   the equation. \[v=\frac{{{V}_{\max }}[S]}{{{K}_{m}}+[S]}\] where, \[{{\text{V}}_{\text{max}}}\]represents the maximum rate achieved  by system  at  maximum substrate concentration, the \[{{\text{K}}_{m}}\]indicates substrate concentration at which rate of reaction is half of the maximum velocity \[({{V}_{\max }}).\]
