Effect of inhibitors on enzymatic reactions

Effect of inhibitors on enzymatic reactions. The following reaction is catalyzed by the enzyme catalase: 2H 2 O 2 ? 2H 2 O + O 2 In a series of experiments examining the effect of inhibitors on catalase activity you obtain the following results (assuming [catalase] remains constant).
