What is the substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
Are enzymes permanently changed in the chemical reactions they aer involved in?
No, enzymes are not permanently changed in the chemical reactions they are involved in. Enzymes are catalysts that facilitate chemical reactions by lowering the activation energy, and they remain unchanged after the reaction takes place. They can be used repeatedly in multiple reactions.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
How do enzymes affect the rate of reaction?
Enzymes speed up a reaction but they are not changed by the reaction. They are a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts for organic biochemical reactions.
What is a substance that is changed in a chemical reaction Called?
A substance that undergoes change in a chemical reaction is called a reactant.
What are products reactants and catalysts?
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
The substances that are produced in a chemical change are called?
chemical reaction is when a substance is changed chemicaly but not physicaly
What is the term for the substance changed during a chemical reaction?
You think probable to the reactants.

What is a Catalyst mean in chemistry?
In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.
Why a substance that speeds up a chemical reaction without being permanently changed itself?
A Catalyst.From wikipedia: "Catalysis is the process in which the rate of a chemical reaction is increased by means of a chemical substance known as a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. The catalyst may participate in multiple chemical transformations."http://en.wikipedia.org/wiki/Catalyst
