Catalase Lab Report

1. The different reaction rates between the potato and chicken liver indicate that one of the substances contain more catalase than the other. The reaction rate between the chicken liver and the hydrogen peroxide was quite fast as opposed to the potato and hydrogen peroxide which was at a slow to a moderate rate. This is most likely due to the fact that cellular respiration occurs more often in animals than plants, meaning that they would have a higher ammount of catalase.

2. Test tube 5 had a greater reaction rate than test tube 4.

In test tube 4, there was a higher concentration of catalase (enzymes) than hydrogen peroxide (substrates). Even though the concentration of enzymes increased, the reaction rate was little to none. Because the

    Lowest? The highest was at pH 7, and the lowest was at pH 2. The catalase enzyme works the best at an optimal pH of 7 (neutral) and works the worst at an acidic pH of 2. How does changing the pH affect the rate of enzyme activity? Does this follow a pattern you anticipated?…

    The hypothesis was proven wrong by the timing and values of the graph. I believe this was caused by the enzyme having to break apart a heightened amount of substrates in the mixed test tubes. This caused the initial data to yield a quicker reaction (on the basest of browning in color) compared to the altered data. The independent variable of this experiment was time, while the dependent variable was the color as the reaction is completely dependent on the duration of time. There were numerous potentially sources of error during this experiment.…

    INTRODUCTION: The objective of this lab is to measure the activity of an enzyme and the effects of environment conditions on enzyme activity. Enzymes are catalysts; agents that speed up chemical reactions by lowering the activation energy required. This means that a catalyst helps reactions occur at a greater speed and lower temperature.…

    The Effects of an Enzyme, Catechol Oxidase, on the Conversion of Four Different Substrates to Pr oduce Benzoquinone. Amir Akhras Lab partners: Monica Elabed, Andres Velazquez, and Roland Rencz Biology 201 Instructor: Dr. Kara Nuss October 28, 2014 ABSTRACT Enzymes are catalysts that speed the reaction of substrates to produce products. They achieve this by lowering the energy of activation (EA) but they do not change the nature of the reaction. The objective of this experiment was to test which of the four substrates will produce benzoquinone based on their molecular formula and absorb the most light.…

    Seven tests tubes were used to find the effect of peroxidase on the rate of reaction. Whether the rate of reaction changed due to the amount of enzyme added was found by mixing two tubes at a time with different measures of peroxidase and recording the absorbance at 470nm on the spectrophotometer in twenty-second intervals. Tube one contained the substrate but no enzyme to be used as a blank, tubes two, four, and six contained the substrate and the dye, tube three contained dilute concentration of peroxidase, tube five contained medium concentration of peroxidase, and tube seven contained concentrated peroxidase. Tubes 2 and 3 were measured with 0.5 ml of peroxidase, tubes 4 and 5 were measured with 1.0 ml of peroxidase and tubes 6 and 7 were measured with 2.0 ml of peroxidase. The results showed that the more peroxidase that was added gave a higher absorbance level in the reaction.…

    The difference between the two graphs is the speed of the reaction. The temperatures of the two tests were very similar throughout the experiment. when doing this experiment one should have a paper towel ready to wipe the side of the test tube to be able to read the temperature. Conclusion: This experiment tested the difference between a untreated and treated catalase enzyme.…

    The second test tube 11 was identified as a gram negative bacteria. The biochemical tests that I performed that were positive were catalase, glucose, SIM, indole, citrate, and urea. First, the catalase test has the presence of an enzyme in the test isolated detected using hydrogen peroxide. Bacteria possess catalase with a small number of bacteria; isolation is added to hydrogen peroxide when bubbles occur. When the bubbles occurred on gram positive bacterium it was a conformation of being positive.…

    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…

    When catechol is in excess and substrate is increased, the rate of reaction increases to a maximum limit due to the inability of the enzyme to work higher than its normal rate of reaction. 3. When the catechol is the substrate in excess and the enzyme increased, the rate of reaction increases exponentially due to the increasing amount of enzymes able to catabolize more…

    Lactate dehydrogenase (LDH) is an oxidoreductase found in both eukaryotes and prokaryotes. LDH catalyses the formation of lactate and NAD+ from pyruvate and NADH, during the last step of anaerobic glycolysis. The reaction is also catalysed in the other direction by LDH during the Cori cycle. This reaction can be assayed using spectrophotometric techniques; peak absorbance of NADH is at 340nm, but the peak absorbance of NAD+ is 259nm (Powers, et al., 2007). Enzyme assays are performed to measure the rate of an enzyme-catalysed reaction, known as the enzyme activity.…

    The prediction for this experiment was: when the temperature hits 80 degrees Celsius, the catechol will be at its optimal absorbance. The alternate hypothesis tested for this following experiment was that there is a significant relationship between catechol and pH. In contrast, the null hypothesis states that there is no significant relationship between catechol and oxidase and pH. This hypothesis will be supported if the rate of catechol oxidase does not increase. The hypothesis was tested by observing the reaction time of catechol oxidase at four different…

    Abstract The purpose of this investigation is to determine whether the temperature can affect the reaction rate of enzyme activity. The enzyme activity was measured by five different temperatures, separated in tubes which later got measured by their height of foam after 10 minutes. Freshly-prepared potato juice was used as the enzyme for catalase. Since temperature is measured by the kinetic energy of molecules, the higher the temperature, the more movement of molecules.…
