Absorbance Experiment With Turnip Peroxidase

Enzymes and Factors That Affect Them Rewrite title Zuryab Rana October 21, 2017 Abstract: In the experiment we used Turnip, Hydrogen Peroxide, Distilled Water, and Guaiacol as my substances. On the first activity, Effect of Enzyme concentration of Reaction Rate for low enzyme concentration, we tested three concentrations of the turnip extract, and hydrogen peroxide. For the Turnip Extract I used 0.5 ml, 1.0 ml, and 2.0 ml. For hydrogen peroxide we used 0.1 ml, 0.2 ml, and 0.4 ml. We used a

Brassica rapa Peroxidase Enzyme Sriya Bhamidipati Abstract. Peroxidase is an enzyme whose main function is to break down hydrogen peroxide. It is rich in content in the organism Brassica rapa, or the turnip. The purpose of this study was to investigate and observe the effects of pH, temperature conditions and the inhibitor Hydroxylamine on Peroxidase ‘s ability to break down Hydrogen Peroxide. By observing the absorbance change of different solutions of differing concentrations of Peroxidase, pH5 buffer

types of alteration to the Gibbs free-energy profile” (Albery, 1976). The experiment that the class worked on was about peroxidase. Peroxidase is part of the enzyme group that presents most living organisms (Ahmed, 2013). Peroxidase interferes with the removal of hydrogen peroxide (Ahmed, 2013). Hydrogen peroxide is a toxic product that have normal metabolism before it causes any cell damages (Ahmed, 2013). Peroxidase has two substrate and both of them must present a reaction (Ahmed, 2013).

The Effect of Substrate Concentration on Enzymatic Reaction Rate of Turnip Peroxidase Introduction 1. Background: Catalysts are substances that increase the rate of a reaction by providing a different mechanism for the reaction to go through in order to lower the activation energy and are unchanged by the end of the reaction. Enzymes, a specific type of catalyst, are proteins that increase the rate of reaction by converting a substrate to a product in biological processes (Burns, 2002). Enzymes

affect the rate of enzymatic reactions? Hypothesis: If the pH is around seven, then the rate of the reaction for the enzyme peroxidase will be the highest. This is because the optimal pH range for the enzyme peroxidase is around seven and at its optimal pH an enzyme functions the best. Variables: Independent ─ pH Dependent ─ rate of enzymatic reaction (measured by absorbance) Controlled ─ amount of enzyme used, amount of hydrogen peroxide used, amount of guaiacol added Control group ─

Affects of pH on Peroxidase Enzyme Claire Bell Biology 1130 Jazmen Myers Section 36 Abstract Peroxidase is a turnip enzyme; it is used in the oxidation of hydrogen peroxide to lower activation energy, speeding up the reaction. The activity of peroxidase is highly dependent on its environment and most importantly the pH level. Peroxidase has been the focus of many recent studies and is believed to possibly reduce swelling among other things. We conducted an experiment testing the effect

boiling and concentration on Horseradish Peroxidase ABSTRACT The purpose of this report is to find out the effect of change in the Temperature, PH, boiling, concentration in peroxidase activity. Peroxidase is an enzyme that converts toxic hydrogen peroxide (H2O2) into water and another harmless compound. In this experiment we use, turnips and horseradish roots which are rich in the peroxidase to study the activity of this enzyme. The activity of peroxidase with change in temperature was highest

lab is to explore the effects of enzyme concentration, substrate concentration, temperature, and inhibitors on reaction rate, respectively. To test each of these factors, four activities were completed. The enzyme from Turnip Extract and the substrate Peroxide were tested. The turnip extract was tested at the following concentrations: .5ml, 1.0ml, and 2.0ml. Peroxide was tested at the following concentrations: 0.1ml, 0.2ml, and 0.4ml. In order to understand the effect of temperature on reaction rate

The preparation for the experiment started by gathering the solutions of enzyme Peroxidase, substrate hydrogen peroxide, the indicator guaiacol and distilled water. Two small spectrometer tubes and three large test tubes with numbered labels. In addition, one test tube rack, one pipet pump and a box of kimwipes were also gathered. Before the experiment, the spectrometer must be set up to use by flipping the power switch to on. Following, the machine was warmed up for 10 minutes and the filter lever
