Matthew Chamberlain Brownhillls Community School An ExperimenTo Investigate The EffectOf Hydrogen Peroxide (Substance) Upon Yeast (Catalase) Background : Catalase is a protein molecule, thats reactions it catalyses are crucial to life. Catalyses converts Hydrogen Peroxide to water and oxygen. Catalase also uses Hydrogen Peroxide to oxidise toxins including Phenols, Formic Acid, Formaldehyde and Alcohols. Catalase is an enzyme found in food such as potato, liver and yeast!. It is used for removing Hydrogen Peroxide from cells. Hydrogen Peroxide is the poisonous by -product of metabolism. The enzyme catalase speeds up the decomposition of hydrogen peroxide (2H O ). Hydrogen peroxide breaks down into water and oxygen. Equation : Catalse Hydrogen Peroxide Water + Oxygen Catalse 2H O 2H O + O It is able to speed up the decomposition of Hydrogen Peroxide because the shape of it matches the shape of the Hydrogen Peroxide. This type of is called an anabolic reaction as the Hydrogen...
