Catalase Lab Report
Catalase Lab
Purpose: To observe the effects of hydrogen peroxide on living tissue and non-living materials, showing the presence or absence of catalase as observed by the presences of bubbles.
Hypothesis: If we pour H2O2 on certain substances, the catalase will break down and bubbles will appear at the surface.
Data table: Name | Time | Observation | Raw Potato | 1 min. 30 sec. | Slow reaction, barley any bubbles. | Raw Liver | 5 min. 30 sec. | Extremely fast reaction, very foamy, Big Bubbles. | Raw Hamburger | 5 min. | Lots of foamy bubbles, fast reaction, bubbles got small. | Cooked Liver | 5 min. | Bubbly fizz, Colored changed. | Cooked carrot | 41 sec. | No bubbles, little fizz. |
Conclusion:
I can accept my

    AP Biology enzyme cataylst lab report

    Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A, B, C, and D. In activity A, the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction, to study the characteristics of an enzyme mediated reaction, and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H2O2 present in a solution. The amount will be the baseline for activities C and D. The purpose of activity C is to determine the rate at which H2O2 spontaneously decomposes when exposed to room temperatures and ambient light for 24 hours. The purpose of activity D is to determine the rate at which catalase decomposes H2O2. After adding H2SO4 for different time lashes, etc., the resulting data will be graphed at which the catalase decomposed by catalase.…

    Effect Of Catalase Concentration Naomi Nikeeta Phagau

    3. Catalase is an antioxidant enzyme, which is naturally produced in most organisms, used to help break down hydrogen peroxide into oxygen and water. The break down of hydrogen peroxide helps prevent the accumulation of carbon dioxide bubbles in the blood. It is considered to have a great impact because it is capable of decomposing millions of hydrogen peroxide molecules. In addition, it uses the hydrogen peroxide to oxidize harmful toxins within organisms, such as formaldehyde, alcohol, and phenol.…

    Formal Lab Report 2 Final

    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.…

    Tetramethylammonium iodide was dissolved in a mixture of of Iodine and 95% ethanol while gently heated in a fume hood. Once cooled, crystals started to form in the beaker, which were then collected and washed with hexane through a series of processes involving vacuum filtration. Then a mixture of 5mh of the crystals and 5ml of 95% ethanol was created and tested on a slice of potato to analyse the iodine content. After, with sodium thiosulphate in the buret, the iodide solution was titrated until it turned orangey-yellow, then had 2ml of starch added to it and titrated again until it turned colourless.…

    Catalase Lab Report

    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…

    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 results of our experiment showed the solutions in both tube 1 and tube 2 increasing in absorbency in the first eight minutes but then tube 1 continued to increase while tube 2 began to balance out. Tube 3, our blank, managed to stay at 0nm the entire twenty minutes. From this data, we can conclude that our hypothesis was supported that EDTA had a greater change in absorption over PTU.…

    Catalase Experiment

    Catalysts are substances that increase chemical reactions while using less energy. They also remain unchanged after use, which enables it to be used repeatedly. Cells have special catalysts called enzymes, which are specialized proteins that help accelerate chemical cell reactions. (Evert, RF & Eichhorn, SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF, Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of cell metabolism that can be toxic to the cell (Evert RF, Eichhorn SE & Perry JB 2013).…
