Because some of the catalyst is rare such as platinum that is use as catalyst to produce ammonia.
you cannot. A catalyst is not a single substance, any chemical reaction can have many different catalysts. Usually these are (different) enzymes, but for instance metal ions or metalic particles can act as catalysts too. Otherwise, you can find catalysts at the chemists.
Catalysts
These are called catalysts.
It was Jacob Berzelius who coined the term catalysts in 1835. While it was Johann Wolfgang who first discovered that catalysts can be used in lighters that was commercially successful in 1820s.
Some of the facts are: 1. Catalysts never get consumed in a reaction 2. Catalysts lower the activation energy of the reaction by providing an alternative path to it. 3. Some catalysts do not take part in reaction. They just provide surface or sites for the reaction to take place.
Usually none.
Environmental changes. Usually drastic ones.
organic catalysts made of protein are called enzymes (these are usually made by living things)nonprotein based organic catalysts are simply called organic catalysts (these are usually synthesized artificially)
Basically oil, usually from petroleum, and polymerizing catalysts.
Catalysts stay in the same form as it was before the reaction.
reactions that are controlled by catalysts
Yes, but usually enzymes are the primary catalysts in the Biological world.

Enzymes, as used in reactions, usually do not causes bond formation. They are usually responsible for breaking of bonds but when used in bond formation, they are commonly catalysts. Catalysts simply provide a lower activation energy and causes the reaction to occur faster. Thus, without catalysts, the reaction (including bond formation) will still occur, just at a slower rater. Thus, bond formation can definitely occur without enzymes (catalysts).
Enzymes are catalysts.
