Title: The affects of hydrogen peroxide on catalase reactions in animal and plant cells at different temperatures and states. Introduction: All living organisms in the kingdoms of life are composed of and depend on cells to function normally. Not all cells‚ however‚ are alike. There are two primary types of cells: eukaryotic and prokaryotic cells. Cells contain organelles‚ or tiny cellular structures‚ that carry out specific functions necessary for normal cellular operation. (Regina Bailey Updated

NaHCO3 and NaCl and calculate a balanced equation for this reaction. Safety: • Wear safety goggles at all time • Handle all chemicals with care • Use equipment like tongs when handling warm/hot objects • If chemicals are spilt on self‚ wash off immediately • Stand at all times Hypothesis: The NaHCO3 will react successfully with the HCl and will form NaCl‚ H2O and CO2. Then be able to work out a balanced equation for the reaction and work out the moles of NaHCO3 and NaCl. Materials:

The first six weeks of the nursing program has forced me to turn myself inside out and examine/analyze a lot about my way of life. It has forced me to look deeply into my communication and listening skills. I have learned many different ways to deal with situations and problems that may arise with my impersonal and Intrapersonal relationships. I’ve been trying out different skills with my roommate and trying to really understand what we do in class by actually doing it. I have always found it hard

The lab today was focused on finding the ratio of reactants to products to be either 1 to 1 or 1 to 2. In our case the reactants was Lead (II) Nitrate and Potassium Iodine. These two when mixed together make Lead Iodide and Potassium Nitrate. We also had to try and find if the number of moles of Lead(II) Nitrate was the same as the final number of moles for Lead Iodine after the experiment. Our data for the lab had pinpoint accuracy. Proved by the data table below Trials Volume of Pb(NO3)2 Mol

catalyst free reaction by stirring reaction mixture of a and b in ethanol at room temperature. Additionally‚ several reactions were performed using various catalysts in different reaction conditions and results are summarized in Table 1. The catalyst free reaction fails to produce selective benzimidazole and conversion of reactants in long reaction time and obtained only 21 % conversion with 13 % selective yield of c after 48 h reaction time (Table I‚ Entry 1). Later on‚ the same reaction performed at

The environmental factors that effected the rate of enzyme reactions were the enzyme concentration‚ pH‚ and temperature. These environmental factors help enzymes break down the poisonous chemicals into harmless substance. When we tested the liver with 2ml of hydrogen peroxide for a normal reaction it showed that it was exothermic. We added more hydrogen peroxide and the reaction rate of the liver was 3. We learned that the catalase is reusable because the liver reacted both times when we put in
