Question

As you increase the temperature of an enzyme-catalyzed reaction, the rate of the reaction initially
increases. It then reaches a maximum rate and finally dramatically declines. Keeping in mind that
enzymes are proteins, how do you explain these changes in reaction rates? Select the single best answer.
At first the reaction rate increases because the temperature increase causes the enzyme to
coagulate. At some point the rate of reaction dramatically decreases because the enzyme and
substrate collisions increase.
At first the rate of reaction increases because the temperature increase causes a decrease in
the number of collisions between the enzyme and the substrate. At some point the rate of
reaction dramatically decreases because the enzyme denatures due to the high temperature.
