Experiment to demonstrate the action of amylase on starch solution Esme Power Plan Scientific knowledge: Substances called catalysts speed up many chemical reactions. Catalysts called enzymes control the metabolic reactions in the body. Amylase is an enzyme; it is present in the digestive systems of many animals. Amylase speeds up the breakdown of long chain starch molecules. I know that the more common enzymes work best at around 37.c as this is our natural body temperature. If this temperature begins to rise the reactions slow down, this will continue to happen until the enzyme is denatured. It becomes denatured at around 60.c, this happens because the enzyme becomes misshapen. This means that the enzyme will no longer work because it will no longer fit. When the two join then you get the chemical reaction. Preliminary work: I watched someone else do this experiment and saw how it was to be done. This...
