What happens or doesn't happen to an enzyme at the end of an enzymatic reaction?
The enzyme still remains and can be used again for another reaction.
Compare a structure of an enzyme before and after a reation?
An enzymes structure is not affected by a reaction. The enzyme has the same structure at the end of the reaction as it did before it took place. Note: Enzyme structures may change during the reaction itself but will return to their original shape etc when the reaction is complete.
What is the difference between a reactant and a catalyst?
A reactant is consumed in a reaction to make products. A catalyst is not consumed during the reaction. It is either not directly involved in the reaction or regenerated upon the end of the reaction. This is the main difference. In addition, catalysts work by decreasing the activation energy for the reaction, allowing the reactants to react more easily.
What end product from a metabolic pathway binds to an enzyme involved in a reaction at the beginning of the pathway. changing the shape of the active site and preventing the enzyme from?
Feedback inhibition
Are enzymes changed in a reaction?
enzymes are not changed when they perform their function. this means that the same enzyme molecule can be used over and over again.
What enzyme is person who is lactose intolerant missing?
Lactose intolerance is the inability to efficiently convert lactose into glucose and galactose, a reaction catalyzed by the enzyme lactase. (A rule of thumb for enzyme nomenclature is that many enzyme names typically take most of the name of their substrate and slap an "-ase" at the end.)

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 simple experiment might you perform to test the hypothesis that an enzyme combines with its substrate when it acts?
in the absences of the enzyme the reaction is very slow,and at the end of the reaction enzyme is separated that shows substrate 1st bind to the enzyme
When did Fort Nassau - South River - end?
The enzyme is unchanged by the reaction.

What is any molecule that speeds up a chemical reaction?
A molecule that allows or encourages a chemical or biochemical reaction, while remaining relatively unchanged by the end of the reaction, is called an enzyme.
What is the difference between a reactant and a catalyst?
A reactant is consumed in a reaction to make products. A catalyst is not consumed during the reaction. It is either not directly involved in the reaction or regenerated upon the end of the reaction. This is the main difference. In addition, catalysts work by decreasing the activation energy for the reaction, allowing the reactants to react more easily.
What end product from a metabolic pathway binds to an enzyme involved in a reaction at the beginning of the pathway. changing the shape of the active site and preventing the enzyme from?
Feedback inhibition
Is the enzyme activity same at 5 and 25 Centigrade temperature in water?
The specific activity of an enzyme at a specific temperature will be dependent on both the temperature the enzyme is operating at as well as the concentrations of the substrates (the starting materials of the reaction that the enzyme catalyzes) and products (the end materials of the reaction) present around the enzyme. However, as a general rule, the activity of an enzyme will be different at at 5 centigrade than it will be at 25 centigrade.
Are enzymes changed in a reaction?
enzymes are not changed when they perform their function. this means that the same enzyme molecule can be used over and over again.
Why is an enzyme unchanged in a chemical reaction?
Enzymes are very efficient catalysts for biochemical reactions. They do not undergo permanent changes and so remain unchanged at the end of the reaction.
