Catechol Oxidase Lab Report
The Production of Benzoquinone from a variety of environmental conditions in potato juice extract

Introduction

The presence of quinones prevents infection of microorganisms because it is toxic to them (Danyk, H, 2013). Quinones are produced by the oxidation of phenolic compound of catechol. Enzymes are used to speed up chemical reactions in cells (Danyk, H, 2013). The enzyme catechol oxidase is used to speed up the production of benzoquinone which is to help in infection prevention. In this study catechol oxidase was combined with potato juice extract and water. To provide more results of the enzymes productivity patterns the solutions; temperatures were changed, alterations were made in pH, and the amount of concentration

The extent of the denaturation of the bonded enzymes is affected by the emphasis of the pH change. In cases where the pH change is very minimal there is the possibility that the correct structure can become regenerated completely from its optimum pH becoming reached again. Ideally this procedure will result in substances that are more basic and acidic to produce less benzoquinone and substances that have a pH of seven, or close to seven, will produce a higher concentration of benzoquinone because of the preferred neutrality that a pH of seven has. When preforming this procedure one must begin with five test tubes that are occupied with the correct amount of substance that has the pH of 4, 6, 7, 8, and 10 which will be used. Once this buffer is created for each tube, 10 drops of potato juice as well as catechol oxidase containing the enzymes must be added and shaken in order to equally distribute all the components so that a possible change in pH can occur. Once placed in a 3 degree water bath the variety of colors in the substances due to the new pH change would have had a chance to completely set, making it possible to determine which pH is ideal for the most amount of benzoquinone to be …show more content…
Being at these temperatures are closest to room temperature, which is 25-degreesF, the enzyme produced best stored at this temperature.

Discussion

Production Of Benzoquinone With Graph Data

Through the group results, seen in figure1, figure 2, and figure 3, the mean brought very similar absorption readings. The catechol oxidase with potato juice extract seemed to vary in production in pH data collected, though there was still gradual increase in production. Temperature solutions showed common production the 70- degrees F temperature and 3-degrees F temperature. As for the number of drops of catechol oxidase added to the solution proved that more of the enzyme present will lead to greater production of benzoquinone.

Common Errors and Ways to Improve

The amounts of drops that were put into the test tubes may not have been exactly the correct amount. This was exemplified through the test tube labeled 70 degrees. The absorption value was 90, most likely because more drops of potato juice extract or catechol were added to the test tube then needed. These unexpected results could be tested by redoing the procedure and being critical about how many drops each test tube was given.

    Purpose: Cells produce toxic wastes, in this experiment hydrogen peroxide, and without some sort of molecule to break it down the cell will die, along with the organism itself. However with the aid of an enzyme, catalase, hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver, a vegetable, and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or improved. If it has improved, the optimum has been discovered and the enzyme will create a higher reaction rate. If above the optimal points, proteins will denature and the reaction rate will remain the same. This is vital for cellular activity for if homeostasis is not reached enzymatic activity will decrease or the enzymes will simply denature and the toxicity within the cell will increase killing the cell.…

    Enzymes are biological catalysts or assistants that consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia oleracea (Spinach), Brassica oleracea (Broccoli), Solanum tuberosum (Russet Potato), Malus domestica (Apple), and Allium cepa (Onion). The five different catalases from the sources will all be used to catalyze Hydrogen peroxide (H2O2). When hydrogen…

    If you’ve ever left a cut up apple out for long, you’ll notice that after a while, it will turn brown. The reason for this is an enzyme named catechol oxidase, a ubiquitous plant enzymes containing a dinuclear copper center (Klabunde, Eicken, Sacchettini, & Krebs, 1998). In this experiment, we used two different chelators, ethylene diamine tetraacetic acid and phenylthiourea to test which would stop the effects of catechol oxidase on potato cells by testing the change in absorbency over time. Our data supported our hypothesis that EDTA would have a greater change in absorbency over time than PTU.…

    These results could have been from many different errors that were made during the lab. The first possible error might have been the different amounts of liver on the discs every trial. Because there was no certain amount that was needed other than coat the disk in the paste there could have been more on one disc than another in each trial, meaning that more liver on a disc equals more enzymes which would make the reaction quicker than the last.…

    We found a study about the effects of glycosylation and pH conditions in the dynamics of human arylsuffatase A. They concluded that lowering pH and increasing glycosylation reduced the flexibility of the enzyme. Also, at acidic pH levels the glycosylated enzyme had a higher conformational stability. This study was similar to ours in that it investigated how pH conditions affect enzyme functionality. They found optimal pH conditions for the enzyme like we did, but they took into account another variable that is that influenced functionality…

    The first lab's primary objective is to observe the different reactions rates amongst the five different catalse concentrations of parsnip. The rate at which the enzyme catalyzes increases in relation to the increase of concentration within the test tubes. By increasing the concentration per total volume, the reaction ultimately increases the amount of contents reacting per second while decreasing the overall activation energy. The procedure involves soaking filter papers in the catalase solution and time the reaction as it makes contact with hydrogen peroxide (H2O2 (aq).…

    For Activity A, we first tested enzyme activity. First, we used an H2O2 syringe to transfer 10 mL of H2O2 into an unlabeled 60-mL cup. Then, we used a transfer pipet to add one mL of catalase solution into the unlabeled 60-mL cup that we put H2O2 in. After that, we observed the solution for one minute. Then we tested the effect of boiling on enzyme activity. First we used a transfer pipet to transfer 4 mL of catalase into a test tube. After that, we placed the test tube filled with catalase in a boiling water bath for five minutes. While we were waiting, we rinsed the unlabeled cup we used earlier when we tested enzyme activity. Then we used a H2O2 syringe to transfer 10 mL of H2O2 into the rinsed unlabeled cup. After five minutes, we transferred 1 mL of the boiling catalase into the unlabeled cup with H2O2 in it with an unused transfer pipet and observed the results. After testing the effect of boiling on enzyme activity, we tested for catalase in living tissue. First, we rinsed the unlabeled 60 mL cup we used earlier. Then, we used a scalpel to cut a small piece of liver. After that, we macerated the piece of liver with a glass rod. When the liver was macerated enough, we put it in a cup with 10 mL of H2O2, which was transferred into the cup with a H2O2 syringe. Lastly, we observed the cup.…

    To study the affect of pH on a food preservative. Sodium benzoate changed into benzoic acid once the 3 M of HCl was added making it a pH of 2, making the solution acidic. The hydronium ion concentration was high enough that it gave a yield of benzoic acid, which, is very insoluble in water and it formed a precipitate in the solution. The end percent yield was 132.352%, this was due to a few flaws in the experiment. During the filtration process of the experiment the funnel was not working properly and not all the…

    The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver, ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm, and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation, this means that the more diluted the solution of 95% ethanol was, the less oxygen gas collected. Controlling a number of factors which include human error, temperature change, pH levels, substrate concentrations and ensuring a controlled experimental environment will work to increase the accuracy of the experiment.…
