You Conduct an Experiment in Which You Add Increasing Amounts

question 64

Multiple Choice

You conduct an experiment in which you add increasing amounts of substrate to an enzyme solution and then measure the resulting reaction rate.You graph your results, plotting the rate of the reaction on the Y-axis versus substrate concentration on the X-axis.What do you conclude from your graph?

• A) The reaction rate is directly proportional to substrate concentration.
• B) The reaction rate is independent of substrate concentration.
• C) The reaction rate increases but then decreases, forming a bell-shaped curve.
• D) The reaction rate decreases with increasing substrate concentration.
• E) The reaction rate increases with increasing substrate concentration up to a point, above which the rate remains constant.
