8. A chemist obtains the following Lineweaver-Burk plots for an enzyme catalyzed reaction in the absence and presence of two different inhibitors, A and B. The linear fit for no inhibition is: 1 ?0 = 302.6 1 [?] + 1.96 × 105 The linear fit for inhibitor A is: 1 ?0 = 757.8 1 [?] + 2.03 × 105 And the linear fit for inhibitor B is: 1 ?0 = 1015.3 1 [?] + 5.95 × 105 a) Determine the values of KM and Vmax for the enzyme. b) After determining the type of inhibition imposed by each of the two inhibitors, A and B, calculate the value of Ki for each. 1
