Biology coursework: Investigating how concentration of hydrogen peroxide affects rate of reaction of catalase in a potato Introduction: In this investigation I will be seeing how the concentration of hydrogen peroxide affects the rate of reaction of the enzyme catalase in a potato. Enzymes are biological catalysts made up from protein. Catalase speeds up the decomposition of hydrogen Peroxide into water and oxygen. Equation for the reaction: Hydrogen Peroxide + Catalase --> Oxygen + Water Properties of an enzyme: Enzyme has a specific shape into which only a substrate of the exact same unique shape can fit. Enzymes can be denatured at certain conditions. These conditions are high temperatures and extreme levels of pH. The bonds that hold enzymes together are quite weak and so are easily broken by these conditions. - Temperature: when the substrate is at a high temperature, the molecules move faster and therefore more reactions take place. An enzyme is also...
