A pesticide inhibits the activity of a particular enzyme, which can therefore be used to assay for the presence of the pesticide in an unknown sample. a) In the laboratory, the initial rate data shown in the table below were obtained. What type of inhibitor (competitive, uncompetitive, non-competitive) is the pesticide? Determine the values of Vmax, KM, and KI. v, M/min x 106 S, M No inhibitor 10-5 M inhibitor 3.3 x 10-4 56 37 5.0 x 10-4 71 47 6.7 x 10-4 88 61 1.65 x 10-3 129 103 2.21 x 10-3 149 125
