You are trying to come up with a drug to inhibit the activity of an enzyme  thought to have a role in liver disease. In the laboratory the enzyme was shown to have a Km of 1.0 x 10-6 M and Vmax of 0.1 micromoles/min.mg measured at room temperature. You developed an uncompetitive inhibitor. In the presence of 5.0 x 10-5 M inhibitor, the apparent Vmax  was determined to be 0.02 micromoles/min.mg. What is the Ki of the inhibitor?
