The same enzyme as in Problem 14 is studied in the presence of a different inhibitor (inhibitor B). In this case, two different concentrations of inhibitor are used. Data are as follows:

a. What kind of inhibitor is inhibitor B?
b. Determine the apparent Vmax and KM at each inhibitor concentration.
c. Estimate KI from these data.
