Most people choose hydrogen peroxide over rubbing alcohol to clean a wound since hydrogen peroxide doesn’t burn. However‚ when hydrogen peroxide is treated on deeper wounds into the flesh‚ it can pose numerous problems to cellular health. When hydrogen peroxide is used correctly to clean wounds‚ it becomes an oxidizer and can be used as a disinfectant to prevent infections. However when used incorrectly‚ hydrogen peroxide can cause oxidative stress on cells. This essentially means that there is an

in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals. An enzyme will only work with one substrate. A substrate is the chemical upon which the enzyme acts in the reaction. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. In order for organisms to survive‚ they must get rid of this toxin. Hydrogen peroxide in plants and animals occurs as a waste product of

acidic‚ the enzyme will quickly denature. Hydrogen peroxide (H2O2) is naturally formed in living organisms‚ however it is very harmful and is broken down immediately by several enzymes including catalase. This enzyme catalyses the breakdown of hydrogen peroxide to water and oxygen. Persons with acatalasemia (a hereditary condition) have extremely low catalase activity and‚ although present worldwide‚ it is more commonly found in Koreans. Hydrogen Peroxide is usually used as a topical disinfectant

to; observe the breakdown of hydrogen peroxide toxin by potato’s enzyme catalase‚ determine factors that influence how quickly the reaction takes place‚ and determine factors that influence how well enzymes function. The first test‚ we were supposed to see what would happen when we add sand in hydrogen peroxide. We filled a test tube with 5mL hydrogen peroxide and we added a pinch of sand into the test tube. For the first test tube we observed that the hydrogen peroxide did not react with the sand

a specific enzyme‚ speeds the breakdown of hydrogen peroxide‚ a toxic chemical produced by cells in the body‚ into water and oxygen (Cain and others‚ 2010). The oxygen can be observed as bubbles coming from the reaction site. Catalase is found in many living tissues of organisms‚ including chicken liver. The purpose of this experiment is to determine what changes in pH‚ temperature‚ and enzyme concentration have on the rate catalase works to break down hydrogen peroxide. If the pH‚ temperature‚ or enzyme concentration changes

higher the concentration of hydrogen peroxide the faster the reaction will occur and the more foam will be produced. Aim: The aim of this investigation is to determine how the concentration of hydrogen peroxide effects the intensity of the reaction. Variables: Independent- The concentration of hydrogen peroxide. Dependant - The intensity of the reaction. Constants – The temperature‚ the amount of liver‚ pH level‚ test time‚ Materials: Solutions of hydrogen peroxide varying in concentration 1

LAB: Substrate Concentration Affecting the Rate of Enzyme Activity: Through the Experiment of Beef Liver Puree and Hydrogen Peroxide Research Question Does different amount of substrate affect the rate of enzyme activities? Purpose To examine how different types of concentration (Hydrogen Peroxide) affect the rate of enzyme activity. Hypothesis We believe that if there is more substrate concentrated‚ then there will be an increase in the rate of enzyme activity. This is because

rate of collision between the enzyme and substrate‚ but this effect is limited. The rate of reaction will increase up to a certain temperature. At this temperature‚ the enzyme activity is the greatest. Changes in pH will results in disruption of hydrogen bond of the protein chain. Hence‚ this will results in changes in shape of the enzymes’ active site that then will reduce the effectiveness of the enzyme and the rate of reaction. Using different type of substrate concentration will also affect

Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very important that it is
