Does ethanol causes greater inhibition of pig liver catalase than of yeast catalase? Introduction In my experiment I am using catalase. Catalase is an enzyme that breaks down hydrogen peroxide (H2O2). Hydrogen Peroxide is a waste product left after aerobic respiration. Hydrogen Peroxide is harmful to cells if not broken down. This means that catalase is present in nearly every cell. Catalase breaks Hydrogen Peroxide down into oxygen and water, as it is an enzyme it is not used up in the reaction Catalase Hydrogen Peroxide ???? Water + Oxygen Catalase 2H2O2 ???? 2H2O + O2 Catalase is an extremely efficient enzyme with one of the highest turnover number of any enzyme (the number of molecules of substrate broken down by a single molecule of enzyme per second.). Catalase like all other enzymes is a globular protein. Enzymes have a very precise (three-dimensional) tertiary structure. This structure is held in shape by hydrogen bonds...
