An enzyme is a biological molecule that catalyzes a chemical reaction. Most enzymes are proteins and the word "enzyme" is often used to mean a protein enzyme, but some RNA molecules also have catalytic activity, and to differentiate them from protein enzymes, they are referred to as RNA enzymes or ribozymes.
Enzymes are essential for life because most chemical reactions in living cells would occur too slowly, or would lead to different products without enzymes.
Like all catalysts, enzymes work by providing an alternate pathway of lower energy for a reaction. This speeds up the reaction, sometimes making it many millions of times faster. Chemically, enzymes are like any catalyst and are not consumed in chemical reactions nor do they alter the equilibrium of a reaction. However, enzymes do differ from most other catalysts in showing much higher levels of specificity.
