An enzyme is sensitive to the environmental conditions. It is affected by various chemical and physical factors. Changes in the environmental factors denatures the enzyme.
4 Variable affecting an enzyme function are as follows:
1. pH: An enzyme is affected by change in pH. Every enzyme has its own specific pH at which it works ideally.
2. Temperature: An enzyme works best at ideal temperature. Increase or decrease in the temperature causes denaturation of enzyme.
3. ATP: Increase or decrease in the amount of ATP also affects the function of an enzyme.
4. Product: Increase or decrease in the amount of product also affects the ideal functioning of an enzyme.
