Why do you say that an enzyme is reusable?

Answer 1

Yes, an enzyme is reusable. Remember that a catalyst speeds up a reaction or lowers the activation energy without being chemically altered in the reaction. An enzyme is simply a biological catalyst so it does not change during the reaction.

The only way to change an enzyme and make it unusable is if it becomes exposed to high temperatures and becomes denatured.This means the active site is damaged and the enzyme is no longer able to attach to substrates and catalyse the reaction.

Answer 2

An enzyme is a biological catalyst. It participates in reaction and after reaction is over it get separated and so it remains unaffected. And so it can be used again and again.

Answer 3

Because they are catalyst and are regenerated / recovered.

Answer 4

Yea, Enzymes are catalysts. And a catalyst is- A substance that increases the rate of a chemical reaction, without being consumed or produced by the reaction.

Answer 5

Because once the product leaves the active site, more substrate can enter. So the enzyme will keep on working until all the substrate is used up.

Answer 6

because they are not consumed, or altered in the chemical reaction.

Answer 7

The products of the reaction are released from the active sites of the enzyme, allowing other substrate molecules to bind with the sites.

Answer 8

because of the shape of the enzyme

Answer 9

yes they are
