Catalase is a ubiquitous enzyme that destroys hydrogen peroxides formed during oxidative stress. concentration levels to the function of hydrogen peroxidase. The objective of this experiment was to measure the difference in product oxygen from the previously stated reaction. The hydrogen peroxide causes a reaction to occur with the liver that is aided by catalase The heat caused the enzymes to denature and the reaction did not occur as efficiently this is the optimal temperature for enzyme function because the enzymes denature above this temperature, causing slower reactions. struction of catalase by oxidation is greatly enhanced by the presence of OH ions in the system. Staphylococci contain catalase, and break down peroxide, produces O 2 and bubble, so they are catalase positive, what distinguish them from streptococci. Beta-hemolytic organisms, such as Streptococcus species (catalase-negative), Staphylococcus species (catalase-positive), and Listeria species (catalase-positive) can be differentiated by their catalase reaction using 3% hydrogen peroxide. Enzymes are biological catalysts that can speed up, and control, chemical reactions that would otherwise virtually never occur at normal body temperature, 37°C. faecalis strain V583 and here report the identification of a chromosomal gene, katA , encoding a heme-containing cytoplasmic catalase.
