An Investigation into how the varying concentration of a substrate affects the rate of reaction of Catalase In this investigation, I am going to explore how varying the concentration of Hydrogen Peroxide (H2O2) affects the rate of reaction of the enzyme, catalase. Background Knowledge Enzymes are organic catalysts. Catalysts are chemical substances that speed up a reaction but remain unaltered throughout the reaction. They are made in all living cells and control the chemical reactions that keep the cell alive as well as speeding up the metabolic processes. Enzymes are proteins and their molecules are made up of long chains of amino acids. Enzymes can be divided into two groups. Intracellular enzymes occur inside cells and control metabolism. Extra cellular enzymes are produced by the cells and achieve effects outside the cell. E.g. digestive enzymes. o Enzymes are specific which means that an enzyme that acts on one substance won't act on another. The substance...
