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

Effect of Temperature on Enzyme Activity Bernard Stepteau Biology Lab 101/Th 8:00am – 9:50am 2-26-2014 Dr Laynes Hypothesis: As the temperature of the enzyme catalase rises the activity of the reaction will decrease. Objectives: The objective is to compare catalase activity at different temperatures. Introduction Catalase speeds the breakdown of hydrogen peroxide. Catalase is present in every plant and animal organ. This is useful because hydrogen peroxide is harmful

Activity of the Enzyme Catalase in breaking down Hydrogen Peroxide and the effect of various factors on Enzyme Activity Introduction The enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (H2O2)‚ which is a toxic chemical to the human body. When hydrogen peroxide is broken down‚ the end products are Water (H2O) and Oxygen (O2). In this report‚ the reaction of catalase to hydrogen peroxide is being tested. Furthermore‚ the effects of temperature‚ concentration

Next‚ for further data‚ MSA results were recorded‚ along with antibiotic observations of demo plates. Lastly‚ with the information gathered‚ it was identified that the unknown sample was Streptococcus salivarius. Introduction: In this lab‚ the exploration of an unknown gram positive bacteria was conducted. What is known about gram positive microorganisms

In experiment one (i.e. the effect of varying substrate concentration on the rate of enzyme-catalase reaction) we tested the hypothesis HA as substrate concentration increases‚ so will reaction rate until all active sites are bound. In experiment two (i.e. The effect of temperature on the rate of enzyme-catalase reaction) we tested the hypothesis HA as temperature increases‚ so will

The data from the experiment demonstrates that the catalase enzyme breaks down the hydrogen peroxide due to its harmful toxicity to the liver. In section A‚ the effect surface area has on the enzyme was tested. The results have proven that as the surface area increases‚ the reaction rate of the enzyme also increases. To illustrate‚ when the liver was ground‚ the bubbles from the reaction reached a maximum height of 150mm in five seconds less than the unground liver which merely reached a maximum

Introduction In this lab‚ the density of 20 glass beads were determined using two different methods and the results were compared to see how close the values were to each other. In first method the volume of each individual bead was measured using the diameter of each bead‚ along with the mass. In the second method the beads we treated as a whole unit. The total mass was measured and volume was measured based on the amount of water that was displaced in a graduated cylinder. Then‚ the beads
