All about Catalysts
A catalyst is a substance that speeds up a chemical reaction without being used up by the reaction. It helps the reaction happen more quickly or at a lower temperature.
Enzymes are natural catalysts in living things. Your body uses enzymes to break down the food you eat. Many factories and car exhaust systems also use catalysts to make reactions faster or cleaner.
