an enzyme does not get used up in a reaction. it is essentially a catalyst. although an enzyme speeds up the rate of chemical reactions by decreasing the amount of activation energy required, it does not in itself change during the reaction.
***Note:: Enzymes cease to function when they denature. This usually occurs by pH level changes, or increased temperatures. This occurs because it causes the bond of the molecule to break and essentially changes the shape of the enzyme. Because an enzyme is a lock and key model, when the shape changes it becomes useless

∙ 15y agoNo. That is the definition of a catalyst (which enzymes are) - not being used up in a reaction.

∙ 13y agoNo. Enzymes are not used up in reactions, as with all catalysts. They lower the activation energy and speed up reaction rate.

∙ 9y agoNo. By definition, they are not used up. They help by making the reaction faster.

Are enzymes used up at the end of reaction?
no
Do enzymes speed up metabolic reaction in organisms?
Yes,enzymes speed up metabolic reaction in organisms.
When are enzymes used?
Enzymes are used in almost every biological reaction that takes place in an organism to expedite the process.
What is the monomer of the macromolecules that speed up a chemical reaction?
Reactions are speed up by enzymes. Enzymes are type of proteins
What is are the proteins called that are used to speed up chemical reactions?
The proteins that speed up chemical reactions are called enzymes. Enzymes function as biological catalysts, facilitating reactions by lowering the activation energy required for the reaction to occur.
Are enzymes used up at the end of reaction?
no
What does reusable enzymes mean?
Enzymes aren't used up or denatured after they catalyse a reaction.
What do enzymes do that is so great?
Enzymes lower the activation energy of a reaction, acting as a catalyst and speed up the reaction. Plus they never get used up, only over and over again.
Do enzymes speed up metabolic reaction in organisms?
Yes,enzymes speed up metabolic reaction in organisms.
How do enzymes speed up biochemical reaction?
Enzymes speed up biochemical reactions by lowering the activation energy of the reaction.
What do enzymes do for a reaction?
It speeds up the reaction time.
Is it true that Enzymes are not consumed during a chemical reaction?
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
How do enzymes affect the reaction in living things?
Enzymes act as catalysts. They speed up the reaction time.
Can an enzyme be re-used?
Yes. Enzymes are catalysts and as such they participate in the reaction without being used up.
What do enzymes to do a chemical reaction?
Enzymes are catalysts in a chemical reaction, they are used in chemistry to increase the speed of a specific chemical reaction. A single enzyme will not speed up multiple chemical reactions, usually it is limited to one reactant.
Is enzymes slow the rate of reaction?
Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.
What do catalystes and enzymes do?
they speed up the reaction.
