∙ 11y agoNo - enzymes are never consumed after a reaction. Enzymes are reusable catalysts that facilitate chemical reactions (such as bonding) - they are not a reactant or product in these reactions.

Can the enzyme be reused or is it destroyed in the reaction?
Yes. Enzymes are pretty much known as catalysts, and the definition of a catalyst is "a substance that increases the rate of a chemical reaction, without being consumed or produced by the reaction." So thus we see the enzyme being active in a reaction but not destroyed. There are exceptions to this, though. If an enzyme is kept in hot, unfavorable temperatures, it will change shape or become "denatured" and may become useless in a very short time.
What happens to an enzyme after it catalyzes a chemical reaction?
Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again.
What do you know about the consumption of an enzyme during a metabolic reaction in the body?
Enzymes are specialized proteins that facilitate chemical reactions in the body by lowering their activation energy, or the energy required to initiate a reaction. They are never consumed by the reaction themselves; therefore, enzymes can be re-used many times. Enzymes are specific to a particular substrate and usually facilitate the reaction by undergoing a conformational change when encountering the substrate, transforming it into a product or an intermediate.
What happens to an enzyme after a biochemical reaction?
The enzyme is liberated free to repeat the action again. That is the beauty of enzymes.
What is the function of enymes?
Enzymes are biological catalysts. They speed up biochemical reaction. During the course of a reaction, the enzyme molecules do not get consumed. At the end of a reaction, the enzyme molecules are ready for another reaction. Enzymes are able to catalyze reactions by decreasing the free energy change (delta G) associated with a biochemical reaction. When the reactants have to go through a smaller free energy change, the products are formed faster.
What is the chemical that helps a chemical reaction without being consumed during a reaction?
ENzyme
At the conclusion of an enzyme catalyzed reaction what does the the enzyme do?
I think it frees itself from the product and is ready to be reused.
In a bio-chemical reaction what are the bio-molecules which are not consumed yet their presence is required?
In every biochemical reaction in the body, a specific enzyme is required to catalyze (speed up) the reaction. These enzymes are required for the reaction to take place, but are not consumed themselves in the reaction.
How do you determine amount of enzyme consumed in a reaction?
There is no catalyst that is consumed in reaction which it is catalysing. In other reactions, eg. breakdown reactions, they do not catalyse their own breakdown! Enzymes are (bio)catalysts mainly as special protein molecules. In the reactions that ARE catalized they are not consumed, otherwise they were not 'catalists' but 'reactants'.
Can enzymes be re-used?
Yes. An enzyme is a catalyst. The definition of a catalyst is "A substance that increases the rate of a chemical reaction, without being consumed or produced by the reaction." Therefore an enzyme is a catalyst and can be re-used. There are exception's in extreme tempartures of course.

Why do you say that an enzyme is reusable?
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.
Can the enzyme be reused or is it destroyed in the reaction?

After a reaction what happens to the products?
Products are formed during reaction. After it they stay unchanged, if not then they are not stable, thus reacting otherwise and hence NO products! at all.
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.
