The Effects on Peroxidase Abstract: Enzymes are catalyst that speed up a chemical reaction that takes place inside a living cell. Enzymes speed up reactions by lowering the activation energy of a reaction. Peroxidase is an enzyme that is crucial in removing Hydrogen Peroxide which is produced as a by-product in some metabolic reactions. The lab was conducted to determine the effects of different factors on enzymes. Multiple experiments such as changes in temperature, concentration, inhibitors, Ph, and difference in the reaction rates were recorded. We divided the different experiments within our groups. Hydrogen Peroxide, Guaiacol, and peroxidase was prepared for the students, and each student used them accordingly for their experiments. Guaiacol …show more content…

Hydrogen peroxide is a harmful substance which could seriously harm cells if left to build up. Subsequently it is needed to discover the ideal conditions required for the enzyme to work accordingly. A progression of experiments were set up to test how temperature, ph, concentration and an inhibitor would influence the reaction rate of Peroxidase. Peroxidase is obtained by the concentrate from a turnip. The technique used to monitor the response amongst Peroxidase and hydrogen peroxide is by acquainting a color with the blend. "The color Guaiacol ties to Peroxidase and ends up plainly oxidized as the hydrogen peroxide is diminished to water." When Guaiacol is oxidized, it changes color to dark brown. A Spectrometer passes light through a substance which then records the absorbance of spectrums. The Dye changes the color according to the rate of the reaction. The Spectrometer records how fast the reaction happening. Utilizing this data, You could hypotheses about the trials. As concentration of Peroxidase increase, so will the reaction rate. If an inhibitor is acquainted with the Peroxidase arrangement, it will diminish the rate of response. Any change in temperature or pH will deform the enzyme and influence the response rate. In this way, the Enzyme will have an ideal pH and temperature where it works generally

    In the lab, Inhibiting the Action of Catechol Oxidase we had to investigate what type of enzyme inhibition occurs when an inhibitor is added. Catechol oxidase is an enzyme in plants that creates benzoquinone.Benzoquinone is a substance that is toxic to bacteria. It is brown and is the reason fruit turns brown. Now, there are two types of inhibitors, the competitive inhibitor and non-competitive inhibitor. For an enzyme reaction to occur a substrate has to bind or fit into the active site of the enzyme. In competitive inhibition there is a substrate and an inhibitor present, both compete to bind to the active site. If the competitive inhibitor binds to the active site it stops the reaction. A noncompetitive inhibitor binds to another region

    In the second experiment 4.2, the effects of inhibitors on the enzyme catechol oxidase were observed. Phenylthiourea (PTU) was the specific inhibitor that was used. The phenylthiourea inhibits catechol oxidase by combining with copper that is a cofactor for the enzyme. The first test tube had the same amount of catechol and phenylthiourea. The reaction from the first test tube didn’t take place. In the second test tube there were 2x as much catechol as phenylthiourea. The reaction took place, but at a slower pace. There was no phenylthiourea in the third test tube, which made allowed the reaction to be accomplished fully.

    Our bodies involve and require many different biochemical reactions, which is achieved through the help of enzymes. Enzymes are proteins in our bodies that act as catalyst as they speed up vital biochemical reactions by reducing the “activation energy” needed to get the reaction going. To sustain the biochemistry of life, enzymes maintain temperature inside our living cells balanced and the concentration of reaction molecules. Enzymes are extremely efficient because they remain remarkably unchanged, therefore have the potential to be used over and over again. They are extremely specific with the reactions they catalyze, like a lock and key and, extremely reactive. The molecule to which enzymes make accelerated changes to is the substrate. The molecule that is present after the enzyme-catalyzed reaction is the product. Most enzymes require specific environmental conditions such as temperature and pH levels to be met in order for them to function properly and efficiently. In the first part of the lab we specifically examined a simple enzyme-catalyzed reaction using catechol (the substrate) which will be catalyzed by the enzyme catecholase and will then result in color change. This familiar color

    This indicated that the effect of high temperature on the activity of peroxidase was irreversible and so if the optimum temperature was restored the enzyme activity will not increase again because denaturation resulted in a permanent change in the shape of the active site of the peroxidase enzyme. In conclusion, the results of this experiment supported the hypothesis that enzymes including peroxidase enzyme are sensitive to temperature changes[George

    An enzyme is a biological catalyst (Purchon 2012). Its most basic function is to speed up the rate of reaction (Enzymes (n.d.). Without the existence of enzymes in living organisms, the process of digestion would take weeks. The function of our muscles, nerves and bones will also decrease in efficiency (Purchon 2012). Therefore, the activities in living systems are dependent on and mostly controlled by enzymes. Similar to other catalysts, enzymes can be reused multiple times, however, their natural properties are easily taken away or altered by heat (Purchon 2012). In order for enzymes to maintain their qualities, they need to be in body temperature and a specific pH (Purchon 2012). The reason why enzymes are so sensitive to heat and pH is because they are protein molecules (Purchon

    In this experiment, we will explore the properties of fresh potato extract in Phosphate buffer pH6 containing the enzyme polyphenol-oxidase and measure the different concentration of this enzyme activity by observing the production of pink/gold melanin, when 0.1% catechol and phosphate buffer pH6 is mixed into the solution. At this stage of the experiment, we are assuming that all other variables that can act as inhibitors of the enzymatic activity such as temperature or pH levels are under control. Fruits and vegetables are known to have small amounts of catechol and polyphenol-oxidase (enzyme), which are the cause of the production of browning effect in the out-layer skin or liquid of the fruit or vegetable when it is damaged.

    The first experiments investigate the order of reaction with respect to the reactants; hydrogen peroxide, potassium iodide and sulphuric acid by varying the concentrations and plotting them against 1/time. An initial rate technique is used in this experiment so ‘the rate of reaction is inversely proportional to time.’ To find the order of reaction in respect to the reactants, 1/time is plotted against the concentration of Hydrogen Peroxide using the equation:

    5 test tubes were prepared for dilution respectively to 5 spec tubes that had the inhibitor and water and ready for the enzyme addition. Recordings were done every 60 seconds for 3 minutes. Reaction rate was then calculated after time ended. After having used the inhibitor, the steps were repeated but replace the inhibitor with water as control and experimented for the rates without the inhibitor. Percentages were graphed by the percentage inhibition versus the substrate concentration for the inhibitor. Part 5 of the experiment was to determine the effect of temperature or pH on the reaction rate. In doing so, each group in the lab was designated a particular enzyme that was exposed in different temperatures (Schultz, 2006). The enzymes were exposed before the beginning of the experiment into these different temperatures: boiling, warm (heat), room temperature, cold (ice bath), and frozen. Each enzyme was allowed back to room temperature before adding the buffered catechol with the 1 ml of enzyme into the spec tube (Schultz, 2006). Reaction rate was then determined from the reading. Absorbance versus time was plotted with the determined initial rate of each
