- Enzymes
- Biological catalysts which speed up reactions
- Catalysts are special chemicals which speed up reaction
- Make reactions faster
- Do NOT change overall reaction
- Build large molecules from lots of smaller ones
- Changing one molecule into another
- Breaking down large molecules into smaller ones.
- Active site is a hole or indentation in the enzyme, which allows other molecules to fit into the enzyme
- Made up of protein molecules made up of long chains of amino acids
- Temperature and PH affect how enzymes work.
- Activation energy= Minumum amount of energy particles must have to be able to react
- Optimum temp= Where the reactions works as fast as possible
- After this enzyme becomes denatured.
- Used in washing machine tablets and slimming food.
- Biological catalysts which speed up reactions
