What else can I help you with?
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?
Enzymes are not destroyed during chemical reactions.
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 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 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 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 the name of the enzyme that doesn't change during a reaction?
Enzymes are organic molecules that are highly specific catylists for biological chemical reactions. Enzymes are not permanently changed by the reactions that they catalyze, although the may transiently change shape a little during the reaction. At the end of the reaction, the enzyme is the same shape that it was at the beginning.
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.
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.
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.
