Serum 2216 Lab Report

592 Words3 Pages

The investigation was carried out to identify the presence or absence of biological molecules in serum 2216. If the concentration in each test tube of the dilutions carried out will be more concentrated then the concentration of the test tube before it, then the color will be at an equal concentration with the other dilutions performed. The hypothesis was wrong because of the difference in concentrations due to the different measurements within the dilutions done. The test for starch was to add a drop of iodine solution to the pipette in the spotting tile. A reducing sugar solutions is add inside a test tube with 3 drops to then add 3 drops of benedicts and plane in a water bath. In a non-reducing sugar 3cm cubed and 10 drops of hydrochloric acid is placed in a test tube for a water bath of 5 minutes to be mixing afterwards. Biurets reagent is added to the protein solution to determine it presence. Testing for …show more content…

The addition signs for each test on serum 2216 illiterates how concentrated the molecule is like purple for example was the most concentrated due to the amount of addition signs in the table. For Macromolecule test 1 and 2 the sample was diluted. Both the concentration and decreased by an equal set of intervals. The volume of distilled water is what was added and the results illustrate how deeply colored each concentration was. Each cup was diluted with the test pertaining to it with a syringe that explain the volume and the concentration is from heating or mixing the sample throughout the investigation. Macromolecule test 1 differs from the second chart by testing non-reducing sugars in the first test and proteins in the second. In depth the lab required to heat the sample at times, mix them, and add them to a warm water bath of 100 Celsius. The following graphs were obtained by following the guidelines within the

    The Unknown Identification Lab was an experiment that provided the opportunity to apply all the tests that were learned in the semester of lab, to identify the two bacterias that remain unknown. Gram- staining and two other tests will be used to identify the unknowns. This experiment is crucial to the understanding of each test, and can benefit in the ability to identify the characteristics of specific bacteria. Having a clearer understanding of the bacteria can further the research of bacteria for medicine, such as antibiotics. The understanding can also help the development of research in the environment.

    For instance, we could not conclude that mitochondrial activity is present in Supernatant II. However, our experiment showed that the boiled corn kernels did not undergo any mitochondrial activity while the raw corn kernels did. This might indicate that raising the temperature might have an effect on the function of dehydrogenase. Moreover, our found that starch granules are present in both sediment I and the “gunk”. Indeed, some parts of this experiment were not successful because the procedure was not followed

    To begin, one must test for monosaccharides. Glucose is necessary, and is needed to be placed into a test tube at a quantity of 5 mL. 3 mL of Benedict’s solution is then added. The test tube is then placed in a beaker of boiling water for five minutes or until the color changes. If the color changes, then it is known that monosaccharides are present in the solution. Next, one will test for starches.

An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.

    The iodine test determines the presence of starch in biological materials. It is predicted that, if starch is not present, the solution with iodine remains yellow. However, if starch is present the solution with iodine becomes a blue-black colour. Plants have starch as the storage polysaccharide (glucose units held together by glycosidic bonds) while animals have the equivalent of glycogen. In this experiment, the dark blue colour is visible because of the helical amylose and amylopectin reacting with iodine (Travers et al., 2002).

    Introduction: The purpose of each experiment is to test which macromolecules are present in each of the different pieces of food, with the foods being apple, potato and hot dog. These experiments, in total, will test for the presence of three of the major four macromolecules, carbohydrates, lipids and proteins. The following are my hypotheses concerning each of the experiments: Carbohydrates - The apple will react, the hot dog will not react, the potato will not react. Starch - The apple will react, the hot dog will not react, the potato will react.

  • Enzyme Assay Lab Report

    706 Words  | 3 Pages

    Enzyme assays are performed to serve two different purposes: (i) To identify a special enzyme by proving its presence or absence in a distinct specimen. (ii) To determine the amount of the enzyme in the sample by monitoring the disappearance of substrate or appearance of product. Enzymes speed up reaction rate by decreasing the activation energy required to start the reaction. Activation energy is the energy required to break certain bonds in the substrate so that other bonds can form. The formation of these new bonds results in the formation of the product by measuring the changes in absorbance due to the substrate (starch) being changed into product by the amylase enzyme.
