Each enzyme molecule is used over and over again.
One of the fastest enzymes is catalase, which is found in liver and elsewhere. It catalyzes the breakdown of hydrogen peroxide into water and oxygen:
2H2O2 forms 2H2O + O2
Each molecule of catalase catalyzes the breakdown of some 40 million substrate molecules in a second.
Many times enzymes have multiple active sites that allow for many simultaneous reactions. For example, it's possible to have a fourth of the number of enzymes as substrate molecules, but the enzyme may have four active sites, resulting in one active site per substrate molecule.
One function. A enzyme is particular about it's substrate, so the enzyme can catalyze one reaction by lowering that reaction's activation energy.
Enzyme is specific
A large number of reactions occur in the cell, many of which requiring enzymes to work. From the creation of the ATP used to energize the cell to the creation of proteins from RNA, each new type of reaction needs its own enzyme to work, and often need dozens if not hundreds of that enzyme to do the reaction at the pace it needs.
George Beadle and Edward Tatum used bread mold, specifically the fungus Neurospora crassa, to demonstrate that each mutation resulted in the loss of a specific enzyme. Their experiments in the 1940s led to the formulation of the "one gene, one enzyme" hypothesis, which posited that each gene corresponds to a particular enzyme that catalyzes a specific biochemical reaction. This groundbreaking work laid the foundation for our understanding of the relationship between genes and proteins.
There is just one enzyme used in the ELISA reaction. This enzyme is linked to the secondary antibody. Commonly used ELISA enzymes are:Alkaline phosphataseHorseradish peroxidase

Enzymes are used to speed up chemical reactions. One example of an enzyme is lactase which speeds the the digestion of lactose.
One function. A enzyme is particular about it's substrate, so the enzyme can catalyze one reaction by lowering that reaction's activation energy.
An enzyme has only one substrate that it works with so it has only one function. This is called a lock and key mechanism. Other things can affect the enzyme such as temperature, pH level and levels of either the substrate or the products. High temperature can denature the enzyme (they are proteins). They can not fit the lock (substrate).

One needs to specifically indicate which enzyme one is referring to. If one is taking about the human body, there are many enzymes that targets and works to help the body.
