Few Properties of enzymes
⇒ Enzymes act as a catalyst . They do not take part in the bio-chemical reaction.However they change the rate of the reaction
⇒ Enzymes are very specific.They only act on particular substrates and are specific in their actions
⇒ Enzymes are complex macromolecules like sugars.They are made up of many molecules combined together.
⇒ Enzymes can only function at an optimum temperature of 35 - 40°C.
⇒ Enzymes are proteins and they behave like proteins.
⇒ Enzymes are active and rapid in action.
