YES
The enzyme still remains and can be used again for another reaction.
The enzyme is liberated free to repeat the action again. That is the beauty of enzymes.

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.
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.
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.
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.
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.
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.
Enzymes are reusable because they can facilitate multiple reactions without being consumed or altered in the process. Their structure allows them to catalyze the same reaction many times, making them efficient and cost-effective in biological processes.
No
In a model of enzyme action, the enzyme can attach only to a substrate (reactant) with a specific shape. The enzyme then changes and reduces the activation energy of the reaction so reactants can become products. The enzyme is unchanged and is available to be used again.
