You do an experiment in the laboratory and add increasing amounts of substrate to a solution
containing an enzyme and a pH buffer. You incubate the container at the optimal temperature for your enzyme. Each time you add more substrate, you measure the rate of the reaction. If you graph the results where the x-axis shows the substrate concentration and the y-axis shows the resulting reaction rate, what will you find over time?
a. The rate of the reaction will proceed with a slope of 1 and continue in a linear fashion indefinitely or until you run out of reactants. b. The rate of the reaction will increase rapidly, taper off, and plateau. c. The rate of the reaction will increase slowly, plateau, and then drop sharply back to zero. d. The resulting graph will be a perfect bell curve. e. There is no way to predict what the graph will look like without more information.
