Some of the important properties of enzymes are:
-
Enzymes are required in minute quantities as compared to the substrate
-
Enzymes show striking specificity. They catalyze specific reactions involving specific substrates
-
Enzymes increase the speed of a chemical reaction. They lower the activation energy of a reaction, thus allowing it to occur at ordinary physiological temperatures
-
The action of enzyme is greatly affected by temperatures.
-
The activity of enzymes is maximum at optimum pH between 4 - 9.
-
Enzymatic activity is affected by H+ ions concentration
-
The rate of reaction is affected by enzyme concentration
-
Enzyme itself is not used up in the reaction it catalyzes so it can be used over again and again
-
Enzymes have a high turn over number. It means the number of reactions that an enzyme molecule can catalyze per second.
