Question

What is enzymes? Details of enzyme

Answer 1

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

Answer 2

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 )
