As the temperature increases, the rate of an enzyme-catalyzed reaction usually:
A)increases constantly.
B)increases up to a point, then decreases.
C)decreases constantly.
D)decreases to a point, then increases.
E)increases, then decreases, then increases again.

Question

Quizplus · Accepted Answer

The rate of an enzyme-catalyzed reaction typically increases with temperature due to increased kinetic energy, leading to more frequent collisions between enzyme and substrate. However, beyond an optimal temperature, the enzyme may denature, causing the reaction rate to decrease.
