it doesn't
actually it does! sorry wiki answers wudnt let me delete that last answer, but enzymes can accelerate or slow down a reaction. and then seperate/ unhinge from the product they created and remain unchanged

What is an enzyme and how does it help speed up a chemical reaction?
enzymes provide an alternative pathway for the reaction,one which is lower than the original activation energy. according to the Maxwell distribution,the number of molecules having the new activation energy is greater,thus there are more molecules which can react and therefore rate of reaction is greater,thus causing enzymes to be catalysts.
What effect does an increase in pH have on enzyme reaction?
It will very likely change it in some way. It's impossible to be more specific without knowing what enzyme and what pH.From the optimum conditions, an increase in pH will increase the number of OH- ions, and these will affect the charge of areas on the tertiary structure of the protein (remember that enzymes are proteins). This will cause a conformational (shape) change in the protein (enzyme), and therefore denatures it, as the active site is no longer complimentary to the substrate. This will lead to fewer Enzyme-Substrate complexes per second when using a lot of enzymes, and will decrease the rate of the enzyme reaction.
What is the relationship between an enzyme and a reactant molecule?
Activation energy is the energy that must be provided to make a reaction take place. The enzyme helps speed up the reaction by lowering the activation energy making the reaction occur at a lower temperature than it would without an enzyme.So when a substrate binds to the active site of an enzyme, the shape of its molecule is lsighty changed. this makes it easier to change into a product. AS student.It lowers it.
How a reaction takes place without an enzyme and then with an enzyme?
Very high activation energy is needed in enzymelss reactions
What are four things that can affect the way enzymes work?
pH, temperature, concentration of enzyme, substrate concentration, etc
After the enzyme catalyzes the reaction is it changed in any way?
Enzymes that enter a reaction do not change in any way but the substrate does.
How do enzymes affect standard free energy?
Standard free energy doesn't change with an enzyme. Rather, the enzyme acts to redirect that reaction in a particular way, lowering the required energy for the reaction to occur but not changing the energy amount involved.
What fits with an enzyme to make a reaction occur?
The substrate fits into the enzyme, much the way a key fits in a lock. Sometimes there are other "modulators" that also fit in the enzyme.

In what way would a defective enzyme affect an organism if it was involved in metabolic reactions that produce ATP?
Non-working enzyme → no ATP → no energy → death.
What happens to a reaction as reactants are used up?
The rate of the reaction slows down

What does cph4 affect?
There is a metabolic enzyme called 6-carboxytetrahydropterin synthase or CPH4 synthase that acts as a catalyst in the following reaction: 7,8-dihydroneopterin 3'-triphosphate + H2O 6-carboxy-5,6,7,8-tetrahydropterin + acetaldehyde + triphosphate To my knowledge however, it does not affect neurological development in any way.

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.
State one way extremely high temperatures can affect biological catalysts found in these organisms?
extremely high temperatures can decrease the rate of enzyme action very quickly ,the enzyme becomes deactivated (enzyme does not work)
What is a substance that affects the rate of a reaction without being changed or used up?
A catalyst is a substance that engages in a chemical reaction but does not remain part of the final products of the reaction. It may, however, be affected in some way as to diminish its effectiveness in further reactions.
