[20 points] An enzyme-catalyzed reaction (KM = 2.7 × 10−3 M) is inhibited by a competitive inhibitor I (KI = 3.1 × 10−5 M). Suppose that the substrate concentration is 3.6 × 10−4 M. How much of an inhibitor is needed for 65% inhibition? How much does the substrate concentration have to be increased to reduce the inhibition to 25%? Constants R = 8
