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

No. That is the definition of a catalyst (which enzymes are) - not being used up in a reaction.
No. Enzymes are not used up in reactions, as with all catalysts. They lower the activation energy and speed up reaction rate.
No. By definition, they are not used up. They help by making the reaction faster.

Are enzymes used up at the end of reaction?
no
Are enzymes affected by the chemical reaction they speed up?
Enzymes are not consumed or altered by the chemical reactions they catalyze. They can be used repeatedly and are not changed in the process. Once the reaction is complete, enzymes are released unchanged and available to catalyze more reactions.
What is the monomer of the macromolecules that speed up a chemical reaction?
Reactions are speed up by enzymes. Enzymes are type of proteins
When are enzymes used?
Enzymes are used in almost every biological reaction that takes place in an organism to expedite the process.
When an enzyme catalyzes a reaction does it become a product?
No, enzymes are not consumed or altered in the reaction they catalyze. They remain unchanged and can be used repeatedly.
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.
Is it true that Enzymes are not consumed during a chemical reaction?
Yes, enzymes are not consumed in a chemical reaction. They act as catalysts, speeding up the reaction without being altered or used up in the process. This allows enzymes to be used repeatedly.
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.
How do enzymes function speeding up in a chemical reaction?
Enzymes function by lowering the activation energy needed for a chemical reaction to occur, which speeds up the reaction. They achieve this by providing an alternative pathway for the reaction to proceed more easily. Enzymes do not get consumed in the reaction and can be used repeatedly.
What do enzymes do for a reaction?
It speeds up the reaction time.
Is an enzyme consumed in a reaction?
No, enzymes are not consumed in a reaction. Instead, they facilitate and speed up chemical reactions by lowering the activation energy required for the reaction to proceed. Enzymes remain unchanged and can be used repeatedly.
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.
Are enzymes used up in the reactions they catalyse?
No, enzymes are not used up in the reactions they catalyze. Instead, enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur. This allows enzymes to be used repeatedly in multiple reactions.
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.
