    Four environmental factors of enzymes were tested in lab. The changing of pH‚ substrate concentrations‚ temperature‚ and an inhibitor (NaCl) and the effects it hade on the enzyme turnip peroxidase. Enzymes are biological catalysts which increase reaction rates by lowering the activation energies of substrates. A substrate is a reactant that interacts with the enzyme. The enzyme and substrate can be viewed as the recently discovered "induced fit model"‚ which suggests enzymes are flexible and dynamic

    Publication No. 11137 Enzyme Activity Guided Inquiry Lab Turnip Peroxidase Introduction Peroxidase enzymes are widely distributed in plants and animals‚ including bacteria‚ to protect cells against the effects of oxidative stress and cell damage due to hydrogen peroxide. Peroxidases are easily extracted from turnips and other root vegetables and provide a model enzyme for studying enzyme activity—how the rate of an enzyme-catalyzed reaction depends on biotic and abiotic factors. Enzyme activity

    In a 1-2 page report‚ address the following. The first part of your report is the Results section of a scientific paper. In this section‚ present the results of your experiment without any interpretation. Be sure to adequately answer the following questions: How did the rate of the reaction change as you changed each of the three variables? If you vary the temperature‚ after a certain temperature‚ the enzymes will become denatured and then the rate will decrease. Each enzyme functions at

    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

    Concentration on Peroxidase ABSTRACT The purpose of this experiment was to inspect the effect of environmental conditions on hydrogen peroxidase. The three conditions tested were the effect of peroxidase concentration on the rate of the experiment‚ the effect of pH of the rate of peroxidase activity‚ and the effect of temperature on the rate of peroxidase activity. During the lab‚ the lab group tested 7 test tubes‚ including 1 blank‚ with different amounts of pH 5 buffer‚ H2O2‚ Peroxidase‚ and Guaiacol

    Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature (El-hilali

    Abstract The enzyme peroxidase has been shown to break down H2O2. Enzymes are known to increase the rate at which a chemical reaction occurs. We looked at factors that affected the breakdown of hydrogen peroxide. These effects are the different temperatures and pH levels the enzymes were placed in. We found that the optimum‚ or best condition‚ temperature for the enzymes tested was about 22 degrees Celsius. The optimum pH level for the enzyme was 7. Introduction Enzymes are biochemical that catalyze
