3 . ) You are running an enzyme assay. You add 1 1 0 - 2 M substrate S to a preparation of 1 1

3.) You are running an enzyme assay. You add 110-2M substrate S to a preparation of 110-7M enzyme E0. The reaction follows the mechanism below:
E+SharrES E+P
Where k1 is the rate constant for the forward reaction to form ES,k-1 is the rate constant of the dissociation of ES, and k2 is the rate constant of product formation.
The values of the rate constants are:
k1=106M-1sec-1
k-1=1000sec-1
k2=10sec-1
(a) At steady state, there is no change in the concentration of enzyme substrate complex concentration over time (i.e.,dESdt=0. Using the values provided, determine the concentration of ES at steady state for this reaction.
(b) What is the overall reaction velocity (i.e.,v=dPdt) for this reaction?
(c) Based on the information given, calculate Km and Vmax for this reaction.
