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

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

Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

Hypothesis: If pH is increased or decreased past the enzyme’s optimum pH‚ the number of products produced by the enzyme will decrease because the enzyme will become denatured. Variables: The Independent variable is the pH of the environment. The uncertainty of pH is ± 1. pH is a unitless value. The Dependent variable is the number of products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant

1. Prepare a lactase enzyme solution by dissolving one lactase enzyme tablet in 200 ml of water in a clean 250 ml beaker. Stir until the tablet has dissolved. Use labeling tape to label the beaker: “Lactase Enzyme Solution.” 2. Prepare a “denatured” enzyme solution by pouring 20 ml of your enzyme solution into a heat resistant tube. The test tube must have the words “Kimax” or “Pyrex” on it. If it does not‚ it is not heat resistant and may break! Use labeling tape to label the test tube: “Denatured

Activity 4 For this activity we were required to perform a library search for resources relating to our field of professional expertise or research interest. My field of research interest is marketing‚ hence I researched Marketing Mix. Logging into the library at Northcentral University (NCU)‚ I typed Marketing Mix into the Roadrunner program using the search limiters: Full Text and Scholarly/Peer Reviewed Journals. Surprisingly‚ the Roadrunner program took me to the EBSCO

AO1 Activity 4 “ Candidates will give a comprehensive description of two ways in which individuals quality of life is affected by ill-health” (3) The two illnesses I have chosen to research that cause ill health are multiple sclerosis and schizophrenia. I have chosen these two illnesses as they both differ completely in terms of how they affect you‚ as multiple sclerosis is more physical and schizophrenia is more mental. Multiple sclerosis Multiple sclerosis is a chronic‚ typically progressive
