As temperature increases enzyme activity increases.
Enzyme activity is at its maximum. The temperature at which this occurs is known as the optimum temperature.
At low temperatures enzyme activity is slow.
At temperatures greater than the optimum, enzyme structure starts to change. The shape of the active site changes and loses the ability to fit with its substrate. The enzyme has been denatured.

What is induced fit?

Fill in the blanks

(0/0)

When a molecule of substrate enters the active site, the

of the enzyme molecule and its active site change slightly, making the active site fit

round the substrate which is called induced fit.
