From the illustration, scenario 1 depicts a normal enzyme operation. Scenario 2 illustrates an inhibitor binding to a second active site, changing the shape of the enzyme. Scenario 3 shows an inhibitor binding to the first active site, directly competing with the substrate. There are 3 line graphs representing each scenario. Match the line graph and the scenario.
