Science coursework Chemistry. Planning: For this investigation I am going to find out what temperature biological washing powder works best at. Prediction: My prediction is that the biological washing powder will work at the temperature 37 degrees Celsius, because that is body temperature and from the research I've got that is the temperature that enzymes work best at. Background Info: An enzyme is any one of many specialised organic substances, composed of polymers of amino acids, that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms. Those enzymes identified now number more than 700. Enzymes are classified into several broad categories, such as hydrolytic, oxidising, and reducing, depending on the type of reaction they control. Hydrolytic enzymes accelerate reactions in which a substance is broken down into simpler compounds through reaction with water molecules. Oxidising enzymes, known as oxidises, accelerate oxidation reactions; reducing enzymes...
