Solved by a verified expert:apply the scientific method to scientific investigationsstate a scientific hypothesis and design a basic experimentconduct an experiment, make observations, and collect datause knowledge of biological principles to correctly interpret qualitative and quantitative informationuse critical analysis to draw conclusionsThis is the culminating assessment in BIOL 102. It is designed to assess your ability to apply theprinciples of the scientific method. For this project, you will complete the activity below. Make sure toaddress all points (questions) associated with the activity.The Effect of low pH on Enzyme ActivityDesign an experiment in which you will test the effect of an acidic fluid on enzymatic activity. (Recall:enzymes are proteins.) To complete this project, it may be useful for you to review the Scientific MethodTutorial (found the Course Content section of the classroom under the Science Learning Center link) andthe Scientific Method lab (Lab 1), so that you can better understand how to design an experiment. It mayalso be helpful for you to review your textbook and Lab 4 (Enzymes). As you review Lab 4, you will bereminded that there are several factors that impact enzymatic activity: pH, temperature, and amount ofreagent. Feel free to refer to observations and information from Lab 4 as you complete the Final AppliedProject (see the questions below). Or in other words, it is OK to use the same enzyme/subtrate/method asyou did in lab 4 (but modify the treatment), or you can search on-line to find a differentenzyme/subtrate/method for measuring enzyme activity.As you design your experiment for this project, please remember that you are trying to examine how anacidic fluid will modify the outcome of an enzymatic reaction. To successfully complete this project, youwill need to identify the question(s) being asked in your experiment and the hypothesis that you aretesting. In your experimental design, you must clearly explain what you are doing. That means thatyou will need to identify the enzyme and the acid, as well as explain your experimental protocol (thisinformation will help you to answer question 2). You must also thoroughly explain how the addition of theacidic fluid impacted the overall reaction process (this information will help you to answer question 4).Hint: Keep in mind that the acid will change the environmental conditions of the experiment (for example,a low pH value could change the shape of the active site on the enzyme protein), without directlyparticipating in the reaction.Lab MaterialsYou may need all or some of the following, depending on your experimental design:Materials from your lab kit:pH paperhydrogen peroxide solution (you can purchase this at a pharmacy if you have used up the bottlethat came with the lab kit)plastic beakers or cupsvinegaryeast (can be purchased at grocery store if you need more)balloonsplastic bottlemarker for labeling of beakersYou may choose to use additional materials (different acidic solutions and/or different organisms and/ordiffernet subtrate(s) if you chose to look at an enzyme other than catalase).Outline submit in assignment folder in week 7.I suggest you include the following in your outline:Name of enzyme you will use, and source (organism)The substrateHow you will measure enzyme activity (method)What type of treatment you will you; type of solution(s), pH, length of exposure, how you will treatyour samplesThe control(s) in the experimentSample sizeMaybe how you plan to present your data (table and/or type of graph)Anything else you would like to get feedback on before you start your experiment.Write a paper that includes the following:1. Title page: title, your name, course name, semester2. Introduction: introduce your project, include needed background information, the question(s) that youare asking and a clear hypothesis for your experiment.3. Design an experiment. Provide a detailed account of the materials and methods used to conduct theexperiment. Also include the methods for data collection and analysis.4. Conduct the experiment and record your results. What did you observe? Present your data in tableand/or graph . Remember to include the unit of measure.5. Use your knowledge about enzymes and acids to interpret and discuss your results. It may benecessary for you to refer to your textbook and/or use other information resources. What effect does theacidic treatement have on the enzyme activity? Looking back, how could you have improved yourexperiment?6. What is your conclusion? Was your hypothesis supported?7. Cite all reference sources used (including text book) and provide a reference section with citations inAPA formatSubmissionSubmit your final applied lab project as an attached Word document in the assignment folder by the duedate specified in the course schedule.Late Submission Policy: Zero points for late submission (a short extension may be granted if youcontact me before the deadline).
