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).

Enzymes are an important part of the digestive system, where they chemically digest food into usable nutrients. Enzymes with different functions are found in many other areas of your body.
The arrangement of it's active site. Some enzymes just provide a place where two reactants can be in a protected environment for the reaction, some enzymes stress bonds of reactant to lower the reaction activation energy and some enzymes have catalytic properties due to the arrangement of the various amino acid R groups in their active site. One enzyme, one substrate(s) and one function. So, many different classes of enzymes. Very much so
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.
no, every enzyme has a different shape giving it a different job or function

One function. A enzyme is particular about it's substrate, so the enzyme can catalyze one reaction by lowering that reaction's activation energy.
A coenzyme is a molecule that helps enzymes to carry out their functions in the body. Coenzymes often act as carriers of electrons or small functional groups during chemical reactions. Examples include NAD+ and FAD which are involved in energy production processes like cellular respiration.
Enzymatic reactions depend on the concentration of the substrate. Once all active sites become filled, the output of product obviously depends on something else. This could be the pH of the solution, the temperature of the solution, or many other factors. Usually, higher temperature means high kinetic energy (motion) of molecules and faster reaction times. However, too hot of a temperature can denature the enzymes active site. Also, different enzymes work more or less efficiently in different pH levels. Also, the overall affinity for the substrate by the enzyme influences the rate. Inhibitors can also affect rates.

Heat would make most enzymes unnecessary as added heat would allow (many) reaction to achieve activation energy without the need of a helping enzyme. In a biological system most enzymes are proteins and as heat denatures proteins the effect would be to destroy their functionality.
