The enzyme's shape fits its substrate's shape, thus allowing the enzyme to catalyze the appropriate reaction. B. The enzyme's active site can change shape in order to match any substrates in need of a catalyst. C. The enzyme is much larger than its substrate, thus allowing the catalyzed chemical reaction to take place inside the enzyme. Use the chart to the right to answer the questions 22-23.
