 Definition: A substance which speeds up a chemical or biochemical reaction which, without the catalyst, would have occurred anyway but at a much slower rate. The catalyst is never used up in the reaction, so that there is always the same amount at the start and the end of the reaction. Enzymes are biological catalysts.
