WebEnzymes. When k2 is very small compared to k–1 the KM becomes a Kd (or in some textbooks this is called a KS ) for the ES complex. A Kd is really an equilibrium constant (Keq ) for a dissociation reaction in which the products are the dissociated form of the reactants. Write the reaction for which this Kd equals the Keq for your reaction. Make a.
