Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.

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?
Enzymes are not destroyed during chemical reactions.
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
What are the starting substances that are involved in a chemical reaction called?
Substances initially present in a chemical reaction that are consumed during the reaction to make products are called "reactants".A "reagent" is a substance or compound that is added to a system in order to bring about a chemical reaction or is added to see if a reaction occurs.Although the terms reactant and reagent are often used interchangeably, a reactant is more specifically a "substance that is consumed in the course of a chemical reaction".Solvents and catalysts, although they are involved in the reaction, are usually not referred to as reactants.
What new substances are formed during a chemical reaction?
The new substances formed during a chemical reaction are called Products.
What is the chemical that helps a chemical reaction without being consumed during a reaction?
ENzyme
Are enzymes affected by the chemical reaction they speed up?
Enzymes are biological catalysts. A catalyst speeds up a reaction by lowering the activation energy required. In other words a catalyst offers an alternative pathway to increase the rate of reaction- it is not consumed during a reaction, or affected.
What is the definition of enzyme?
Enzymes are proteins that are able to catalyze (i.e accelerate) biochemical reactions. During the course of a reaction, the enzyme is able to convert a substrate to a product but the enzyme does not get consumed in 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.
Can an enzyme be reused after catalyzing a chemical reaction?
Yes, enzymes can be reused over and over again for catalyzing chemical reactions because they are not consumed during the reaction, so they will remain in solution to quicken the reaction again with fresh substrates. Think of an enzyme as a container that forces its substrates to be in closer proximity to each other, which increases the chances of collisions and, in turn, the chances for a reaction to occur faster.
What is anothor name for a protein catalyst that speeds up chemical reaction during cellular respiration?
Enzymes
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?
Enzymes are not destroyed during chemical reactions.
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 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.
Are enzyme catalase reusable?
yes, enzymes are reusable.
Are enzymes affected by the chemical reaction?
No, enzymes are considered catalysts in a reaction. This means that they help a reaction occur that may not otherwise. By definition catalysts (and therefore enzymes) are NOT used up during a reaction. They assist the reactants and then are regenerated to be used again (whereas the reactants become new products are are consumed). They do this by lowering the activation energy (the energy needed to cause the reaction). They lower the activation energy by a variety of ways, usually by getting the involved reactants into a close proximity, and by causing a physical or chemical change to them, allowing the reaction to proceed.In our bodies enzymes are essential as the body has a very specific environment (temperature, pH range, etc) that make several of our vital reaction impossibly slow without them to help us along. Without them, the reactions that must occur millions of times each second in our bodies could take weeks, months, or years to happen otherwise. At that scale, our life would be impossible.
Lower a chemical reactions activation energy?
A catalyst lowers the activation energy without being consumed during a reaction
