BRAINCAKEEffect of Temperature on Enzyme Activity
As the temperature is increased the kinetic energy of the molecules increases and the molecules move faster and collide more often and with more energy.
There are more frequent and more effective collisions so more enzyme-substrate complexes are formed in a given time.
At the optimum temperature, the rate of enzyme-substrate complex formation is a maximum.
