Figure 14. Example of enzyme action model
The speed of enzyme action is affected by many factors:
1- Concentration of the enzyme.
2- Temperature.
3- pH.
4- Substrate concentration.
1- Concentration of the enzyme
If there is an increase in the amount of the enzyme, the speed of the
reaction that is catalysed will also increase.
2- Temperature
If the temperature becomes too high, the enzyme will be deactivated
and its catalytic action will cease. The effect of heat on enzymes is of
