Carbamide peroxide

peroxisome is to break down biological compounds (such as fatty acids, foreign materials…) by transferring the hydrogen atoms from these compounds to molecular oxygen. As a result, peroxisomes generate hydrogen peroxides. Then, in order to protect the cell from the damage of hydrogen peroxides, they will be degraded by catalase, one of the most important enzymes of peroxisome, to water and oxygen. As a result, peroxisomes have many functions such as beta oxidation of fatty acids from a long chain of

How do various factors, pH, enzyme concentration, ionic concentration, substrate concentration, and temperature, effect turnip peroxidase absorbance/ transmittance rate? The initial experiment was testing the effects of pH buffers (3,5,7,9,and 11). If the pH buffers of 3, 5, 7, 9, and 11 are tested on the turnip peroxidase, the enzyme will function best, and the reaction rate will be the fastest, under conditions of a neutral pH because the cytoplasm of most cells has a pH of about seven and usually

The enzyme lab was used to determine the different factors that could affect the productivity of an enzyme. In the lab, the reaction between the hydrogen peroxide and the liver was an exothermic reaction because the temperature of the test tube rose when the hydrogen peroxide was placed into the liver. Heat is a form of energy and the temperature rose as the reaction progressed. In the test tube B, the temperature rose from room temperature to around r30ºC showing that it was an exothermic reaction

Investigate the effect of chemical reaction with different temperature on the activity of the enzyme catalase and hydrogen peroxide. he temperature of (potato) catalase with hydrogen peroxide ((H2O2) are independent variable.Hydrogen peroxide (H2O2) is by product of the chemical reaction that take place in cells (toxic to cell structures) but with the help of the enzyme catalase that toxic substance is converted into harmless oxygen and water. The dependent variable is the increase/decrease to measure

Effects Temperature and Substrate Concentration have on Enzyme Catalase Activity Abstract Enzymes are protein catalysts, which is a substance that speeds up the rate of a chemical reaction. The need of breaking down hydrogen peroxide into oxygen is growing because of the harmful toxins present. In the first experiment we hypothesized that as the substrate concentration increased, so did the reaction rate, therefore allowing more oxygen to be produced is less time. The first experiment mixed each

Objective The objective of this experiment is to study the effect of varying temperatures on the enzyme catalase by measuring the oxygen production as it breaks down hydrogen peroxide. Introduction Enzymes are used in our daily lives in many ways. From industry to agriculture, enzymes play a necessary role in everything from bread to laundry soap. In medicine, enzymes can speed up, slow down, or block cellular reactions in the body. Enzyme reactions can be measured as a diagnostic tool. Enzymes and

of salt each catalysts solution contained, the rate of enzyme activity would decrease when applied to hydrogen peroxide. This was tested by measuring (up to 240 seconds) in room temperature of 21 degrees Celsius how long it would take for each filter disk (dosed with the various salt and potato catalase solutions) to float off of the bottom of the beaker that contained hydrogen peroxide. The results of the experiment showed that enzyme activity decreased with higher salt concentrations, that being

30 B7 11/20/15 Liver Enzyme Lab The Effect of pH and Temperature on the Efficiency of Catalase Abstract: In order to determine how pH and temperature affect the liver enzyme catalase, an experiment was conducted. Catalase breaks apart hydrogen peroxide producing water and oxygen. Using an O2 sensor to measure how much additional oxygen is added into a sealed Nalgene bottle, we could determine the enzymes effectiveness. Three variations of temperature were tested: cold, hot and room temperature

found in nearly every living organism. The essential function of catalase is to decompose hydrogen peroxide to produce water and oxygen. This enzyme also plays a major role within the protection of the cell from the oxidative damage that the reactive oxygen species are capable of causing. In addition, catalase is known to have the ability of chemically converting substrates such as hydrogen peroxide at the rate of approximately 5 million molecules to water and oxygen per second. In terms of its biochemical

consumed in the process. 2. When hydrogen peroxide was added to the liver, a chemical reaction took place. Catalase enzyme in the liver acted as the catalyst in this reaction that decomposed harmful hydrogen peroxide into the safe products, oxygen gas and water. When the reaction occurred, oxygen gas formed bubbles and escaped, while water was left behind. 3. The factors that influenced the rate of the chemical reaction between the liver and the hydrogen peroxide were temperature, pH, and substrate concentration
