2. Inhibitor kinetics A pesticide inhibits the activity of a particular enzyme A, which can therefore be used to assay for the presence of the pesticides in an unknown sample. In the laboratory, the initial rate data were obtained and it was determined that an enzyme catalyzed reaction follows competitive inhibition with vmax=2.00104minmol,Km=8.68104M and Ki=1.53105M. After 50ml of the same enzyme solution in part (a) is mixed with 50ml of 8104M substrate and 25mL of the sample, the initial rate observed is 18mol/min. What is the pesticide concentration in the unknown sample assuming no other inhibitors or substrates are present in the sample
