Based on the graph of an enzyme-catalyzed reaction, which of the following could be used to increase the reaction rate beyond point C?

1. increase the amount of substrate

2. add more water

3. increase the temperature

4. decrease enzyme concentration

Answer 3. As Vmax has been achieved, increasing the substrate concentration would not help. Raising the temperature may increase the rate within physiological limits as temperature affects enzyme kinetics.
