Catalysts

A catalyst speeds up a reaction without being used up, so it can work again and again. Enzymes are the catalysts made by living things: each speeds one reaction, such as breaking starch into sugar or letting sugar combine with oxygen in our cells at body temperature, without a flame. Catalysts in industry save energy, and a car's catalytic converter turns poisonous exhaust gases into less harmful ones.
