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.
Yes. An enzyme is not used up in a chemical reaction. Once an enzyme does its job in a chemical reaction, it is able to move on to another chemical reaction that is the same.

What do you call a special protein that help change substances during chemical reactions?
Enzymes are special proteins that help change substances during chemical reactions by speeding up the reaction process without being consumed in the reaction.
What does reactants mean in science?
Reactants are the substances that participate in a chemical reaction and are consumed to produce products. They are the starting materials that undergo chemical changes during the reaction.
What is a chemical reactants and the products in the reaction?
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
Which of the following statements about enzymes is not true A are catalysts B almost all enzymes are proteins C operate most efficiently at optimum pH D destroyed during chemical reactions?
D. destroyed during chemical reactions. Enzymes are not destroyed during chemical reactions; they remain unchanged and can be reused multiple times.
What is the definition of reactants?
Something that reacts to another substance.
Are enzymes unchanged during chemical reactions and reusable?
Enzymes are unchanged during chemical reactions as they act as catalysts and do not participate in the reaction itself. Enzymes are reusable as they can catalyze multiple reactions without being consumed in the process.
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 true in enzymes?
Enzymes are biological catalysts that speed up chemical reactions in cells. They are highly specific, meaning each enzyme catalyzes a particular reaction. Enzymes are not consumed or changed during the reaction and can be reused multiple times.
What do you call a special protein that help change substances during chemical reactions?
Enzymes are special proteins that help change substances during chemical reactions by speeding up the reaction process without being consumed in the reaction.
What is the chemical that helps a chemical reaction without being consumed during a reaction?
ENzyme
Can an enzyme be reused after catalyzing a chemical reaction?
Yes, enzymes can be reused multiple times to catalyze the same chemical reaction. Enzymes are not consumed in the reaction but instead facilitate the reaction by lowering the activation energy. They can continue to function until they are denatured or degraded.
What is the name of the enzyme that doesn't change during a reaction?
The name of the enzyme that doesn't change during a reaction is unchanged, as enzymes themselves are not altered or consumed in the reaction they catalyze. Instead, enzymes facilitate the reaction by lowering the activation energy required for the reaction to proceed.
What are some characteristics of reactants?
Reactants are the substances present at the beginning of a chemical reaction. They are consumed during the reaction to yield products. Reactants typically undergo a transformation in their chemical structure or properties during the reaction.
What does reactants mean in science?
Reactants are the substances that participate in a chemical reaction and are consumed to produce products. They are the starting materials that undergo chemical changes during the reaction.
What is a chemical reactants and the products in the reaction?
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
How is a catalysts different from a reactant?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while a reactant is a substance that participates in a chemical reaction and is consumed. Essentially, a catalyst speeds up a reaction without being changed itself, while a reactant is consumed during the reaction.
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.
