They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. They are known as biological catalysts (substances which speed up reactions but which do not get used up themselves) Enzymes help to turn the substrate into the product. The enzyme has an active site that helps it to recognise its substrate in a very specific way. Just like a key only fits into a specific lock, each enzyme has its own specific substrate.
