Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

Factors affecting enzyme activity ::
1. TEMPERATURE ::
✳The temparature at which enzymes shows its highest activity is know as optimum temperature.
✳Enzyme activity declines both below and above the optimum temperature.
2 .Hydrogen ion concentration (PH) ::
✳A rise or fall in PH reduces enzyme activity.
✳Some enzymes act best in acidic medium. other in alkaline medium.
✳For every enzyme there is an optimum PH where it's action is maximum.
3. Concentration of Substrate ::
✳Increase in substrate concentration, increases the velocity of the enzymatic reaction.
✳The reaction ultimately reaches a maximum velocity. which is not exceeded by any other rise in concentration.
