The effect of enzyme concentration on the rate of reaction of catalase Introduction: Enzymes are globular proteins, with a complex 3D shape formed by the sequence of amino acids. Enzymes act as biological catalyst and control all aspects of metabolism. There are two types of metabolism. (1) Anabolism (synthesis) e.g. photosynthesis (2) Catabolism (breakdown) e.g. respiration Enzymes increase the rate of reaction by the reducing the activation energy. The activation energy of a reaction is the energy, which all living organisms require for the molecules to react together. Once the activation energy in reduced the enzyme binds to the substrate to form an enzyme-substrate complex. The enzyme combines to the substrate at a specific place known as the active site. The active site of the enzyme is only a small fraction of the molecule, which consists of 3-12 amino acids. It is a feature of the tertiary structure of the protein molecule, the enzymes increase...
