What is enzymes? Details of enzyme
Answers
Enzymes are bio-chemical catalysts that alter the rate of reaction not participating in the reaction.
Few Characteristics 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.
⇒ These enzymes are affected by hormones secreted by endocrine glands
Enzymes :
★ These are bio catalysts. Here bio means living and catalyst are ysed to increase rate of reaction.
★ These are proteinaceous. [ Except ribozyme, ribonuclease - P ]
★ These helps in increasing the rate of reactions [ say metabolism ].
★ These aren't able to start any reaction.
★ These can't change equilibrium of the reaction but helps in reaching equilibrium at a faster rate.
★ These are very specific.
★ These are highly efficient. [ Turned over number → Number of substrate molecules converted into product per unit time. ]
★ Active site : Site to which substrate binds. [ Tertiary structure ]
★ Before reaction ( Amount and structure of enzyme ) = After reaction ( Amount and structure of enzyme )
