In some cases |
- A big substrate molecule fits into the active site - A bond breaks - Two smaller product molecules are made |

Enzymes have specificity for their substrate |
- Only one particular type of substrate molecule can fit into an enzyme's active site. This is like the way only one type of key will fit into a particular lock. - This means each enzyme is specific for its substrate molecules. |

What makes enzymes work best? |
Each enzyme works best at - a particular temperature, known as its optimum (best) - its optimum pH At low temperatures the enzyme and substrate molecules have less energy. They do not move very fast so they do not collide very often. The rate of reaction is low. |
