Interactive Question 7.2 Cite some experimental evidence that indicates that membrane proteins drift. A good form of experimental evidence is Fluorescence Recovery After Photobleaching, aka FRAP. In the FRAP process, membrane proteins are labelled with a green fluorescent protein, and part of the plasma membrane is “bleached” with a laser, causing them to lose their fluorescence. The part that was bleached will eventually become fluorescent again, as molecules drift in by diffusion.…
A sketch or view of test setup and arrangement of gauges and loading protocol should be presented. It is not clear the location of gauge 1 and 2 listed in Figure 11. Why the results of two mentioned gauges are presented in comparison with analytical one? Are the both of them comparable? Why the results of two gauges are different?…
Mold is fungi that are found outdoors and inside homes. Molds grows exceptionally well on paper products and in moist dark environments. Nevertheless, mold is found in every environment, including dry conditions and reproduce year round. Areas in which mold are found include greenhouses, saunas, farms, mills, construction areas, basements and showers. According to the Center of Disease Control (CDC) mold thrives on three conditions.…
The study of microbiology requires not only understanding the microscopic organisms, but also the understanding of lab techniques and procedures used to identify, control, and manipulate microorganisms. The identification of microorganisms is not only important in microbiology lab, but also in the medical field to identify an agent of a disease that will help treat the patient by using the correct antibiotics to kill off the host. In this unknown lab report, techniques and procedures learned in the microbiology laboratory during the semester that was performed to test ones practical understanding of microbiology. The sole purpose of the unknown lab is to demonstrate understanding of the experimental methods and lab techniques learned during…
Project 3 Identification and Synthesis of an Unknown Ionic Compound Mitchell Morgan CEM-161-007 Josh Ward 28th October 2015 Abstract The chief objective of this experiment was to identify the unknown compound. The following tests were conducted to eventually establish the identity of the compounded: qualitative solubility tests, anion and cation tests, flame test, and the formation of a precipitate. The physical properties of the unknown ionic compound found that it has no smell and was soluble in water.…
The focus of this lab was to identify an unknown organism based on its characteristics and the results from each of the tests. There will be various of test to choose from in order to identify the unknown organism, which will eliminate numerous possibilities and narrow it down to one. All the fundamental skills that we have learned and practiced in the lab will be used to perform on our unknown such as aseptic technique, microscopic examination, the use of differential media, and determining if it’s positive or negative. Performing aseptic techniques is the most crucial step that requires the utilizing of transferring, inoculating, and storing bacterial cultures and media. Aseptic technique is defined as procedures that prevent contamination…
Explain in great detail how you could easily test the substances and re-label the three bottles. (Hint: Ammonium ions do not provide a distinctive flame color). To easily test the substances and re-label the three bottles you could create a flame with the substances and use diffraction glasses to find the substance’s…
When finding out unknown bacteria you have to go through several steps to figure out what it could be. I was given unknown bacteria number 28 and asked to run different testing to identify exactly what this bacterium is. I ran 6 test to determine my unknown. These test includes: Gram Stain, SIM, Sucrose, Citrate, MAC, and EMB. Each one of these test are different and they will give a positive or negative feedback which is how we will know which bacterium I have.…
The bacteria used in the experiment are Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Klebsiella pneumoniae, and Salmonella pneumonia. These all bacteria will be culture in the nutrient broth. The first stage is making Nutrient Broth. Weigh out 5.8 grams of nutrient broth powder.…
Purpose: The overall goal of this lab was to perform a procedure on E. Coli which involved transferring genes that encoded for the green fluorescent protein into E. Coli to see if the transferred genes would make a difference on the growth and whether or not the bacteria would glow under UV light. Hypothesis: If the bacteria with the pGLO plasmid was grown on a plate containing LB and ampicillin then the bacteria will grow but not glow under UV light. If the bacteria with the pGLO plasmid was grown on a plate containing LB, ampicillin, and arabinose then it will be able to grow and glow under UV light. If the bacteria without pGLO plasmid was grown on a plate containing LB and ampicillin then it will not be able to grow or glow under UV light.…
Each and every recyclable plastic has a number identity depending on the type of plastic additives it has inside. The identity indicates which plastics can be sorted to be recycled together because different numbered indicators melt at different temperatures and have different additives in it. This identity creates some issues in recycling plastics in the their facilities limiting the kinds of plastics they can recycle. Cernansky says “But not all plastic can be recycled, and only about 6.8 percent of the total plastic used in the U.S. actually goes that route” (Cernansky 1) in general it is very difficult to have plastic recycled properly. She concludes with a solution to get educated on…
Catherine Delker Honors Chemistry – Yellow Blue Beaker Experiment Lab Report 8/20/15 Blue Bottle Experiment Problem: The purpose of this lab was to determine the oxidation rate of the Methylene blue solution when tested with varying amounts of solution. Background:…
Discussion There were four goals for Project 11: Identification, Properties, and Synthesis of an Unknown Ionic Compound. The first goal was to identify the unknown compound, the second goal was to determine the reactivity of the compound, the third goal was to determine the quantitative solubility of the compound in water, and the fourth goal was to find the percent yield of a product from a reaction involving the unknown compound. Determining the identity of the unknown compound was achieved by performing a variety of tests for the physical properties of the substance. Some of these properties, such as melting point and chemical structure, could be discovered by making a few immediate observations of the substance. The unknown compound…
Stuff Matters is a book by Mark Miodownik where he explores the different origins and properties of materials that are in our daily lives. The materials around us are taken for granted, thus not many people can answer the question of why the materials look, feel, and act the way they do. A prime example is plastic. Polymers, or plastics, are considered one of the six classes of materials that has changed the world. Plastic is held with high status in the material world because of its extensive formability, giving it properties that allow it to be formed for certain purposes.…
The plastics are all pretty and skinny. They also differ from…
