Enzymes lower the activation energy of a reaction (that is, the amount of energy that is needed in order for the reaction to occur).
Without an enzyme, a reaction may need so much energy that it is impossible to obtain in a normal biological timespan. With enzymes, reactions require much less energy, so that they can occur hundreds of times a second.
Enzymes can achieve this catalysis in many ways - for instance, if a reaction involves two substances combining to form one, the enzyme can bind each substance in a specific site that forces them close together, making the reaction much more likely to occur and requiring much less energy for the substrates to locate and approach one another.

Relate the shape of an enzyme to its ability to help in a chemical reaction?
The shape of an enzyme will determine its ability to help in a chemical reaction. These proteins that will break down substance in the body and catalyze chemical reactions.
How is a specific enzyme able to catalyze a specific reaction in the cytoplasm of a single cell with many different enzymes?
An enzyme binds to a specific substrate (reactant) for the reaction catalyzed.
How does the enzyme catalyze the reaction?
An enzyme catalyzes the reaction by changing the shapes of the molecules that stress the bonds holding together. Therefore the bond is weaker and will break down faster.
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.
The ability of an enzyme to catalyze a reaction is not affected by?
excess cofactor
What a protein that can catalyze a chemical reaction?
enzyme
What is a protein that catalyze a chemical reaction?
enzyme
A protein that can catalyze a chemical reaction?
enzyme
What is the main thing an enzyme does to catalyze a reaction?
The main thing that an enzyme does to catalyze a reaction, is to lower the energy of reaction.

Will the enzyme maltase catalyze the chemical reaction that breaks down hydrogen peroxide?
Of course not.Enzymes are specific.Moltase breaks Moltose into glucose only.
What effect does substrate and enzyme joining have on chemical bonding?
enzyme catalyze the biochemical reactions by lowering their activation energy. An enzyme which take part in such reaction wont be lost or gained any chemical structure and it would be the same after the reaction.
What chemical reactions within the body sometimes require special proteins called to catalyze the reaction?
The (general) name of proteins that makes chemical reactions inside the body work is 'enzyme'. Enzymes have a 'catalyst' function. There is one for each specific biological reaction.
How many different chemical reactions can a single enzyme catalyze?
1
An enzyme will continue to catalyze a reaction until what happens?
Until the reactants run out
Is an enzyme used up by the reaction it catalyze?
Enzymes are highly efficient catalysts, and only small quantities are needed to catalyze the reaction of relatively large amounts of materials.
