Enzymes are catalysts because they speed up chemical reactions |
Most of these reactions, such as: - photosynthesis - respiration - protein synthesis Take place inside living cells. Enzymes can be used to catalyse the same type of reaction many times. |

The shape of an enzyme is vital for its function |
Enzymes, like proteins, are folded into a particular shape. The shape of one particular area of the enzyme molecule, called the active site, is very important - The substrate molecules fit into the active site - This brings them together so they can form a bond - This makes a bigger molecule |

Enzymes active site |
The two substrate molecules fit side by side into the enzyme's active site, a bond forms between them, and one large product molecule is formed. |
