Enzymes In Biochemical Reactions — Role & Importance

By Jasper Brown
A graph of reaction rate over temperature. The reaction rate increases until the temperature reaches Tc, at which point there is sharp decline to a lower rate, then the rate increases with temperature from this lower position.

A reaction is catalyzed by an enzyme. As the temperature rises, it is observed that the reaction becomes faster and faster until some critical temperature, TcT_{c}. At this temperature the rate of reaction plummets, but afterwards it rises again. A graphical depiction of this is shown above. What is the cause of this drop in reaction rate?
