boiling and concentration on Horseradish Peroxidase ABSTRACT The purpose of this report is to find out the effect of change in the Temperature‚ PH‚ boiling‚ concentration in peroxidase activity. Peroxidase is an enzyme that converts toxic hydrogen peroxide (H2O2) into water and another harmless compound. In this experiment we use‚ turnips and horseradish roots which are rich in the peroxidase to study the activity of this enzyme. The activity of peroxidase with change in temperature was highest

AP Biology Lab: Catalase (Enzymes) Abstract In this laboratory exercise‚ studies of enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme

spent three years trying to perfect Z-Trim to be smooth because he made it out of tough hulls of corn‚ oats‚ and rice. He first crushed the hulls with a solution of hydrogen peroxide. He washed the peroxide off in centrifuge. After this step it was still too large‚ so he put the pieces back through the first step of the hydrogen peroxide and the centrifuge. That made it smooth. Now‚ it is a fine‚ white cellulose powder that can be made into a gel by adding water. Inglett also developed Oatrim.

EFFECT OF CONCENTRATION ON REACTION RATE The aim of this experiment is to find the effect of varying the concentration of iodide ions on the rate of reaction between hydrogen peroxide and an acidified solution of potassium iodide: H2O2(aq) + 2H+(aq) + 2I⁻ → 2H2O(l) + I2(aq) The course of this reaction can be followed by carrying it out in the presence of small quantities of starch and sodium thiosulfate solutions. As the iodine molecules are produced they immediately react with the thiosulfate

bacterium was a gram negative or a gram positive. After performing the gram stain‚ I concluded that by the appearance of purple spherical clusters resembling grapes that is was a gram positive cocci. A Catalase test was then performed using hydrogen peroxide. A positive catalase test was observed when bubbles started to form on the culture distinguishing Staphylococcus spp. form on the culture distinguishing Staphylococcus spp. from Streptococcus spp. Finally‚ a Mannitol Salt Agar was streaked

Determining the Catalytic Properties of the Enzyme Peroxidase Extracted from a Turnip Under the Conditions of Temperature‚ pH‚ Boiling and Competitive Inhibitors By Robin Caserta BIO 101 September 30‚ 2013 ABSTRACT The enzyme‚ peroxidase‚ extracted from a turnip was tested for its efficiency in binding to its substrate and its stability under several conditions. To do this‚ we tested effects on peroxidase activity‚ first‚ with different amounts of the enzyme‚ next at temperatures of

scientific principle is the filtration of the purified water. The reason for the ash being boiled was to extract the iodine ions. D. The scientific principles behind step D was the adding of hydrogen peroxide solution to the remaining solution we had. The reason for this was so that the hydrogen peroxide could convert the iodine ions into iodine. E. In step E you had to transfer the mixture to a separating funnel. You then had to add 10cm3 of cyclohexane which was the scientific
