A catalyst helps speed up a chemical reaction.
For example, a catalyst of acidified dichromate ions or acidified permanganate ions can help speed up the reactions of oxidation of an (alcohol into an aldehyde?) etc.
Catalysts are used for reactions which would usually be of a very slow speed.
Catalysts are classified into several types based on their states and functions. They can be categorized as homogeneous catalysts, which exist in the same phase (liquid or gas) as the reactants, and heterogeneous catalysts, which are in a different phase, often solid. Additionally, catalysts can be classified based on their function, such as acid-base catalysts, redox catalysts, and enzyme catalysts in biological systems. Another classification is based on the mechanism, including contact catalysts and supported catalysts.
Chemical manufacturers use catalysts because they speed up the rate of the reaction taking place, without effecting the chemical formation of both the reactants (which form the product) or the catalyst itself.
There are mainly two types of catalysts: homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase. Homogeneous catalysts are usually dissolved in the same solvent as the reactants, while heterogeneous catalysts are typically solid catalysts in contact with the reactants.
Enzymes are natural catalysts, these natural catalysts speed up reactions.
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
but all catalysts aren't enzymes...
Enzymes - biological catalysts.
For neutralizing bases, as catalysts, as dehydrating agents etc.
Enzymes are catalysts.

Of course not, catalysts doesn't react.
Enzymes are natural catalysts, these natural catalysts speed up reactions.
