Experiment: To Investigate the Effect of Temperature on Trypsin Introduction Thousands of chemical reactions take place in our cells. We need these reactions to happen quickly to keep us alive. Luckily for us there are chemicals called enzymes. Enzymes make reactions happen at a much faster rate. Chemicals that speed up reactions are called catalysts. Since enzymes speed up chemical reactions in our cells, they are often called biological catalysts. During our experiment, we will use photographic film that is coated with gelatine. As gelatine is a protein, the trypsin, which is a protease, will dissolve it. Trypsin is a protease or an enzyme that is used for breaking down protein molecules into amino acids so that they can be dissolved into the stomach. All enzymes are proteins and are all effected by temperature. Proteases Protein (Gelatine) -------------> Amino-Acids Enzymes come in two types: Breakers: Sometimes we need to break down large molecules into smaller...
