Many enzyme -catalyzed reactions are consistent with a modified version of the Michaelis -Menten mechanism in which the second step is also reversible. For this mechanism obtain an expression for the rate of formation of product and find its limiting behavior for large and small concentrations of substrate using steady state approximation
