of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate that is added to the enzyme‚ the higher amount of

bleach‚ hydrogen peroxide‚ and isopropyl alcohol‚ were tested. This was done by creating aqueous solutions of staphylococcus epidermidis bacteria and a chemical agent. The solutions were then incubated on an agar petri dish for 24 hours. The quantity of staphylococcus epidermidis bacteria colonies that were grown were used as an indicator of how effective each agent was in killing the bacteria. Each bactericidal agent has its own mechanism for killing bacteria. Both bleach and hydrogen peroxide are

reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius. Along with variations in temperature‚ the experiment involved different amounts of the two solutions being used. Using a spot plate containing 12 wells the different mixtures of hydrogen peroxide and water were

was performed by adding hydrogen peroxide to sand. Due to the fact that the sand was not soluble in the hydrogen peroxide‚ no reaction thus no catalyst were present. Manganese dioxide was also added to the hydrogen peroxide creating a moderately fast reaction thus leading to believe that an enzyme was present to lower the activation energy and speed up the reaction. When the manganese dioxide was added to the hydrogen peroxide it catalyzes and breaks down the hydrogen peroxide and oxygen gas thus creating

Investigation Aim: The aim of the investigation was to investigate the effect of substrate concentration Hydrogen Peroxide H O (in %) on the rate of reaction of the enzyme catalase (in 1/mean time). Prediction: As the substrate concentration (hydrogen peroxide) in % increases the rate of reaction in 1/mean rate increases until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The rate steadily

promotes the conversion of hydrogen peroxide‚ a powerful and potentially harmful oxidizing agent‚ to water and oxygen. Catalase also uses hydrogen peroxide to oxidize toxins including phenols‚ formic acid‚ formaldehyde and alcohols. Catalase is an example of a particularly efficient enzyme. Catalase has one of the highest turnover numbers for all known enzymes (40‚000‚000 molecules/s). This high rate shows an importance for the enzymes capability for detoxifying hydrogen peroxide and preventing the

speeds up the decomposition of hydrogen peroxide The students have studied that Hydrogen peroxide is a jeopardy to metabolism if it’s not obliterated. Enzymes are proteins produced by living cells of that act as catalysts which affects the rate of biochemical reaction by speeds up the breakdown of hydrogen peroxide into water and oxygen gas. The students have formed a hypothesis toward this experiment. If the speed of decomposition of hydrogen peroxide is related to the temperature then in high temperature it will
