Name a factor that affects enzyme activity pH or temperature
Define an enzyme's optimum temperature The temperature at which the enzyme has the highest ACTIVITY.
Explain what happens when an enzyme is denatured. The active shape changes shape so it cannot bind to the substrate. (1 mark) The enzyme activity lowers/stops (1 mark)
