While the structure of an enzyme can, and often does, change over the course of a reaction, after a reaction has completed, enzymes are returned to their starting state. It is worth noting that certain cofactors (such as ATP or GTP) may also need to be replaced in order for the reaction to procede again.

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 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.
Why must the enzyme exist in a specific type of environment in order to function properly?
Enzymes that are sensitive to changes in their physical or chemical environment, such as changes in pH or temperature will change their shape if placed in suboptimal environments. Most enzymes are proteins, and it's a protein's shape that determines their function. Change the shape, and the enzyme is denatured, and can no longer function for its purpose adequately.
What effect has pH on enzymes?
pH influences enzyme activity by affecting the shape and charge of the active site. Most enzymes have an optimum pH at which they function most effectively. Deviating from this pH can denature the enzyme and reduce its activity.
Are enzymes altered in the process of catalyzing chemical transformations?
Enzymes are not altered in the process of catalyzing chemical transformations. They act as catalysts by lowering the activation energy of a reaction, allowing it to proceed faster, but remain unchanged themselves at the end of the reaction.
Do enzymes change shape after reaction occurs?
no

What substance takes place in an enzymatic reaction but does not change shape?
Enzymes. Substrates react with the active site of the enzyme and are broken down. Enzymes stay the same throughout the reaction.
Do enzymes change shape to move substances across the plasma membrane?
Enzymes and the substrates they work on fit like a lock and key, if you change the shape of the key, the lock won't open. An enzyme whose shape changes is no longer able to activate the reaction of the substrate.
Are the enzymes used up by the reaction?
an enzyme does not get used up in a reaction. it is essentially a catalyst. although an enzyme speeds up the rate of chemical reactions by decreasing the amount of activation energy required, it does not in itself change during the reaction.***Note:: Enzymes cease to function when they denature. This usually occurs by pH level changes, or increased temperatures. This occurs because it causes the bond of the molecule to break and essentially changes the shape of the enzyme. Because an enzyme is a lock and key model, when the shape changes it becomes uselesssources: my brain
What should not be used to indicate a chemical reaction?
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.

How does an enzymes interact with a substance?
Enzymes interact with substrates by binding only with specific substrates. Enzymes will then alter the shape of the substrate in order to induce reaction.
What to enzymes do?
Enzymes attach to things called substrates to help speed up the reaction. Only certain enzymes match the shape of certain substrates.
What refers to the situation in which the binding of a substrate to the enzyme causes a change in the enzymes shape facilitating an enzymes function?
This situation is known as induced fit. When a substrate binds to an enzyme, the enzyme's shape can change to better accommodate the substrate, creating a more optimal environment for the catalytic reaction to occur. This induced fit mechanism helps enzymes to be more specific and efficient in their function.
Why are enzymes three dimensional shape so important?
An enzyme's three dimension shape is important to the binding that occurs between the enzyme itself and its specific substrate, forming the enzyme-substrate complex. In order for the enzyme to create a reaction it is important that the shape of the enzyme binds the substrate to the active site where the chemical reaction occurs. One other thing to consider is the shape that the enzyme takes that allows only its specific substrate to bind and not any other molecule.
Are enzymes permanently changed in the chemical reactions they are involved in?
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
