Catalase is an enzyme that breaks down hydrogen peroxide into water and gaseous oxygen the research outlined in this paper investigated this property of catalase and verified whether or not this enzyme/substrate relationship follows the michaelis-menten relationship this was carried out by observing the effects catalase had on graded. This lab however, when calculating the x intercept by: this value is considerably closer to the observed value in the graphs, and it is reasonable to say that this is the true michaelis constant for this reaction error analysis: through this lab, we have thoroughly processed the enzyme-catalyzed reaction of hydrogen peroxide by the enzyme. Investigate the effect of substrate concentration on the rate of activity of the enzyme catalase.
The purpose of this lab was to observe enzyme kinetics and to see how the presence of an enzyme can catalyze a reaction differently depending on the varying levels of enzyme, temp, and ph catalase is an enzyme that is found in the liver, and its purpose is to get rid of reactive oxygen species (ros) substances in the body. Students use an oxygen gas sensor or pressure sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase theory enzymes are proteins that catalyze chemical reactions by reducing the reaction’s activation energy, this is important in many reactions.
