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.
What happens to an enzyme after a biochemical reaction?
The enzyme is liberated free to repeat the action again. That is the beauty of enzymes.

Do enzymes change shape after a reaction occurs?
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.
How does the non-competitive inhibitor decrease the rate of an enzyme reaction?
Noncompetitive inhibitors decrease the rate of an enzyme reaction by bonding to an enzyme somewhere other than the active site, deforming it and permanently disabling the enzyme, so that enzyme can never function again, so the rate of reaction decreases.
Can an enzyme be use over again?
Yes they can. Once the chemical reaction has taken place, and the product is formed, the enzyme releases them and combine with other reactants to undergo another chemical reaction.
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.
One important feature of enzymes is their specificity What statements describes what this means?
Enzymes are specific: -they only speed up one type of reaction. -they will work over and over and over again until they've been denatured. -you can denature an enzyme with: heat, acid and base. -the structure of an enzyme determines its job.
Can an enzyme be reused after catalyzing a chemical reaction?
Yes, enzymes can be reused over and over again for catalyzing chemical reactions because they are not consumed during the reaction, so they will remain in solution to quicken the reaction again with fresh substrates. Think of an enzyme as a container that forces its substrates to be in closer proximity to each other, which increases the chances of collisions and, in turn, the chances for a reaction to occur faster.
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.
Can a substrate be reacted again?
No
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.
