Potato Catalase Lab

Improved Essays
1.)During the lab and based on recorded observations it can be deduced that the enzyme catalase found in potatoes only reacted to hydrogen peroxide.
This is do to the fact that before 10 ml of hydrogen peroxide was added to each test tube residing 3 potato samples and the designated liquid, no reaction was observed. Thus demonstrating the catalase's inability to react to vinegar, soda, water, detergent, and Na OH. Furthermore, shortly after the hydrogen peroxide was added to the liquids of diverse ph levels, a rapid and prominent throng of bubbles began to appear, which demonstrates the mediate reaction the hydrogen peroxide had on catalase.

2.)The change in an enzyme's structure or shape, is commonly due to extremely high or abnormal temperatures and unsuitable ph levels. Furthermore, one example of an enzymes shape changing is when they become denatured or in other words non functional. This occurs due to high temperature exposure, that hinder and deforms the enzyme's shape, resulting in complete loss of function and mobility.

3.) when human blood comes into contact with hydrogen peroxide, it rapidly begins to bubble, this is do to hydrogen peroxide converting into oxygen gas and water when in contact with the enzyme catalase(in blood ). Furthermore, if a cut was exposed to hydrogen peroxide the skin surrounding the scrape would not react

Furthermore this reaction is called enzymatic browning, that typically occurs optimally at warm temperatures and at pH levels between 5.0 and 7.0. However if lemon juice with a high acidic ph level were to make contact with these phenolase enzymes, their ability to function or under go enzymatic browning would cease to exist. This similarly occurred in the hydrogen peroxide and vinegar reaction, due to vinegars highly acidic ph level and 0 reaction to hydrogen peroxide, which is exactly like the lemon juice and apple

    The reactants that enzyme act upon with the substrate and the enzyme will bind together into the active site. The catalyst is important to the enzyme that breaks down the hydrogen peroxide and oxygen gas, where the rate of reaction of the catalyst will increase the temperature until it has reached the optimum temperature above 37°C is reached. If the optimum temperature has reached above 37°C then the kinetic energy and substrate molecules will begin to denature. The purpose of the lab was to determine the effects different temperature in yeast and hydrogen peroxide in a catalyst enzyme on reaction rate. There were many sources of errors that occur in the lab from having just one trial, using the same thermometer for each solution and inaccurate timing.…

    According to PubChem (2015), hydrogen peroxide (34.01468 g/mol) consists of two hydrogen atoms and two oxygen atoms that can be seen in liquid and powder form. The liquid form is visible to the human eye as a colorless liquid with a clear odor that could be described as irritating or distinct. The aqueous molecule can be broken apart fairly easily, as it is a very unstable molecule with a bent shape. When coming in contact with certain organisms’ tissues and organs, H2O2 is broken down by catalase to prevent major damage to the tissues.…

    Studying the reaction of the enzyme catalase in different temperatures The purpose of this experiment was to measure the speed and the effectiveness of the enzyme catalase. The enzyme catalase purpose is to break down harmful substances and turn them into oxygen and water. The substance in this environment was hydrogen peroxide, and the study was to see how well the chicken liver would work if it was in a boiled environment, room temperature environment, an acid immersed environment and a basic environment.…

    The first piece of liver tested was we submerged it in boiling water for roughly five minutes, we got a zero reaction rate after testing it because the extreme heat totally changes the structure of the enzyme no longer having the catalase enzyme but something different. We also submerged a piece of liver in a beaker of ice and was submerged for roughly 5 minutes we then tested it and got a reaction rate of about 1 and a small amount of bubbles created because the low temperature slowed down the speed the reaction could happen. The last test for this part was we had liver in just warm water and then tested it and we had a reaction of about a 5 and a ton of bubble almost overflowing the test tube it's because the enzymes weren’t exposed to heat that could change them but heat that would speed the reaction. The last part of our lab part D was what does pH affect the catalase activity. Our first test tube had a basic solution with a pH of 10 and the reaction rate was about a 4.…

    A beaker about half full of hydrogen peroxide was prepared for the later reaction. We used four test tubes to make solutions of 2.5 mL of distilled water and 2.5 mL of Catalase. Since our goal was to measure catalase reaction time under varying temperatures, we prepared four different temperatures for the Catalase to be submerged in before it was mixed with the hydrogen peroxide. The different temperatures included a cold sample (0 degrees Celsius), a room temperature sample (21 degrees Celsius), a body temperature sample(37 degrees Celsius), and a boiling sample (103 degrees Celsius). We made sure to measure the exact degrees in Celsius.…

    In this part of the lab, we pour 20 mL of Hydrogen Peroxide and 1 mL of yeast catalase in the reaction chamber and then submerge it in the water bath. After it was done, it can be concluded that the gas levels increased because when we first started timing it, the gas levels were at 76, but as time went by, the gas levels started to increase and in the end of the last interval, the gas level increased all the way up to 100. This result occurred because there were many active sites that were empty for the substrate to bind to and since they binded to the active sites, it started increasing a lot at the beginning. However, when the active sites started getting more occupied, the substrate could not bind to as much active sites, so the gas levels started to increase alittle less as time went on and in the end, there was no active sites that were…

    In this experiment the effects of the peroxidase enzyme will be observed. Peroxidase is an enzyme that is largely contained in turnips, horseradish roots, and potatoes. This enzyme rids cells of peroxide forming water and oxygen. Peroxidase also aids in the oxidation of guaiacol into tetraguaiacol. The peroxidase (turnip extract) and substrate guaiacol will be mixed and the reaction rates will be monitored under the different conditions.…

    However, when the substrate concentration was increased, the intensity of color stopped increasing due to the enzymes being unable to to process at a faster rate. All of the alternate hypothesizes were supported; in the experiments, section one (with Figure 1) had an optimal temperature at approximately 24°C; section two (with Figure 2) had an optimal pH at approximately pH8; in section 3 (with Figure 3) the color continued to increase with the addition of more enzymes; and in section 4 (with Figure 4) the color continued to increase until it reached a maximum velocity with the addition of more substrates. One desired retrial for the experiment would be to test for more points after 20 drops of potato juice in Figure 3. Understanding the effects of how these properties alter the ability of the catecholase enzyme could allow for better insight into decreasing time needed for biochemical reactions, proper food storage, and the condition of…

    Introduction: Enzymes have a huge effect on the human body and other organisms. Enzymes are catalysts that are used to accelerate the reaction process by lowering the activation energy. For this experiment the catechol oxidase was extracted from potatoes. The enzyme is called catechol oxidase because the oxygen is reacting to catechol. Catechol oxidase causes the browning of the fruits and vegetables because the compound is toxic to the bacteria.…
