Answer 1

In this graph, the reaction rate of the substrate has leveled off, and the enzyme and the substrate are available in equal amounts. Which is the most effective way to obtain a faster yield of product without raising the amount of energy needed for the reaction?
A. Lower the temperature within the environment so that a lower activation energy is needed.
B. Add more of the enzyme to increase the reaction rate.
C. Increase the activation energy by making more substrate available to the reaction.
D. Inhibit the substrate by blocking the active site, which increases the concentration of enzymes.

Answer 2

B. You graph shows that the enzyme has become saturated, meaning that as we move to the right on the x-axis the amount of the substrate increases. At some point (where it levels off) there is more substrate than the enzyme can handle.
