    Abstract The aim of this experiment was to investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius.

    Do mistakes lead to discoveries? I think that mistakes do lead to discoveries like‚ when Percy Spencer was standing near the Magnetron and his candy bar was melted then realized that the Magnetron was heating the area up then‚ he asked for some popcorn kernels and put them close to the Magnetron and they popped minutes later‚ so then the microwave was created about 20 years later through many mistakes. In “Lost Cities‚ Lost Treasure” a man named Heinrich Schliemann was digging in the ground of

    pH Affecting on Amylase Enzyme Is there a difference in the concentration of pH in the amylase enzyme activity? The null hypothesis would be that there will be no difference in the concentration of pH and alternative hypothesis would be that there will be a difference in the concentration of pH. The predication if that there will be a difference in the concentration of pH. The pH affects on enzyme activities‚ one of the enzyme that was used in the process was amylase. When a serial dilution was

    Catalase Lab Introduction: Catalase is an enzyme normally found in many plant and animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also‚ some cells use catalase to destroy cellular debris or worn out organelles. In this lab‚ we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism:

    correlation between catalase concentration and the rate of reaction. This occurs because as the enzyme concentration increases‚ there are more enzymes available to catalyze substrates. More enzymes means more reactions can take place at a time‚ thus a faster rate of reaction. Overall‚ based on the results of table 2.0 and graph 2.0‚ it is prevalent that there is a positive correlation between the concentration of enzymes and the rate of

    Rate of Enzyme Activity: Through the Experiment of Beef Liver Puree and Hydrogen Peroxide Research Question Does different amount of substrate affect the rate of enzyme activities? Purpose To examine how different types of concentration (Hydrogen Peroxide) affect the rate of enzyme activity. Hypothesis We believe that if there is more substrate concentrated‚ then there will be an increase in the rate of enzyme activity. This is because we assume the more substrate an enzyme gets

    DISCUSSION: Bromelian added to Gelatin: Bromelian is an enzyme found in pineapples. When Bromelian is added to gelatin it breaks down the protein and does not allow the gelatin to solidify. There are several factors that can cause an enzyme to slow down or to completely stop reacting. For example‚ temperature and pH can effect enzyme activity. Canned pineapple juice and fresh pineapple juice were used to see how the enzyme would react differently. In fresh pineapple juice the Bromelian have would

    Enzyme Kinetics Examples and Problems 1. An enzyme is produced for producing a sun protection lotion. Given kinetic data for the enzyme reaction with Vm=2.5 mmol/m3.s‚ Km=8.9 mM and So=12mM‚ what would be the time required for 95% conversion in a batch reactor? 2. An enzyme was assayed at an initial substrate concentration of 10-5M. The Km’ for the substrate is 2x10-3M. At the end of 1 min‚ 2% of the substrate had been converted to product. a. What % of the substrate will be converted
