Penicillin is hydrolyzed and thereby rendered inactive by penicillinase, an enzyme present in some penicillin-resistant bacteria. The mass of this enzyme is 29.5 kD. The amount of penicillin hydrolyzed in 1 minute in a 10 mL solution containing 100 g of purified penicillinase was measured as a function of the concentration of penicillin. Assume that the concentration of penicillin does not change appreciably during the assay. (a) Plot v versus....
