Register to read the introduction… 30 µl measurements of 0.4, 0.8, 1.2, 1.6 and 20 mg/ml were added into their own sample of the 3 ml Bradford Assay, 30 µl of water was added to a separate sample of Bradford Assay and 30 µl of the dilute liver homogenate was added to its own sample of Bradford Assay and left for 3 minutes. The absorbance of the standards and the diluted homogenate samples were recorded to create a standard curve. From this equation, the protein concentration of my sample was determined. Class averages were also obtained (Clendening).
Y= 0.52x + 0.186 , R2= 0.9572
Protein to DNA ratio was calculated by dividing the determined average protein concentration of the homogenate by the given DNA concentration for all three Bos taurus homogenates (Clendening).Original homogenates were used to digest Glycogen. First, 50 µl of 8 mg/ml amyloglucosidase was added to 50 µl of homogenate to create a

Here we see that the kidney homogenate had the highest concentration of triglycerides followed closely by the liver homogenate.
In order to obtain values for glycogen, free glucose and total glucose concentrations had to be calculated using the glucose standard curve. Once these numbers were known, subtracting free glucose from total glucose came out to the amount of glycogen. Figure 4 shows free glucose levels, where the liver had the highest amount and the kidney the lowest. Figure 3 provides glycogen concentration, where again the liver has the highest levels, but the heart homogenate has the lowest.
To conclude, each cell type of the Bos taurus had varying levels of macromolecules according to the experiments performed in these

    Gram Negative Unknown Lab Report #20 BIOL 3444-008 Giang Nguyen TA: Malini Kotak 11/05/2014 Abstract The experiment is conducted in order to identify a randomly given unknown gram-negative microorganism. By comparative analysis of biochemical tests that were performed throughout the semester to find out its characteristics and determine the identification of bacterium out of four potential unknown was given. To figure out the characteristics, T-streak was performed to isolate the sample from broth to a Tryptic Soy Agar plate, along with an additional slant in case something wrong with the original plate that can possibly affect the result.…

    The aim was not met as the results were not valid because of the errors that had occurred during the experiment. The hypothesis stated that the amylase will break down the starch into simple sugars, and it will leave the dialysis tubing into the surrounding water, and that the 25oc cylinders will create better results as the 60oc cylinders will denature the enzyme. The hypothesis was not supported but as the results were not valid, the hypothesis was not refuted either. To determine if the hypothesis was supported or not accurately means that the experiment needs to be done again without errors. The results could not be used as findings as they were not accurate of how amylase performs in the body.…

    The objective of the biuret test was to find solutions that contain protein. The solutions that turn violet in colour display the presence of protein in them (Rocco, 2006). As shown in Table 3 above, we can see that two of the solutions we used in this lab experiment turned violet including protein solution and the unknown solution. This indicates the presence of protein in both of these solutions. We know that protein solution was the positive control of this test and since it had a colour change, it indicates that the biuret test was done…

Next, I added one drop of Biuret solution into each tube. Then, I recorded the result, if the substance changed purple then it contained proteins. Only stomach two and three had a positive trace of protein.…

    As a group we have taken two sterile plastic vials and placed a cup of Drosophila medium powder into each one. After adding a cup of the medium with added half a cup of distillated water into the plastic vial, which allowed the medium to dissolve into it. We allowed a few minutes for the media to be absorbed and afterwards we applied a cotton plug to close the entrance to the vial. Anesthetizing the Drosophila flies In the lab, we had the fruit flies already asleep in a green bucket filled all the way up with ice.…

Introduction The fundamental core of all biology emanates from evolution, as the great evolutionary biologist Theodosius Dobzhansky once said "Nothing in biology makes sense except in the light of evolution"(1973). Therefore, studying the phylogenetic relationships of different organisms offers numerous advantages that go well beyond those of just pure research.…

    Through this experiment we measured how fast a chemical reaction occurs, by changing the degradation rate in Albumin when added to different enzymes. Albumin is a protein found in egg white, which is considered to have important storage and nutritional functions. Albumin has also been used in medicine to treat heavy metal intoxication. We ran Albumin through four different conditions to see which would make the Albumin degrade faster. We predicted that the Albumin would degrade with pepsin the fastest since it is essential for digestion of substances in the stomach.…

    The job of the human body’s immune system is to fight against infection by detecting and destroying foreign bacteria and viruses, usually to much success. However, the immune system isn’t perfect, and can make mistakes. Sometimes, the immune system confuses a friendly part of the body for a pathogen, and begins attacking its own cells (Petrov, 2011). When these events occur, the body has contracted what is known as an autoimmune disorder. Autoimmune disorders have been rapidly growing problems in today’s society, and a great deal of importance has been put towards understanding both their causes, and treatments.…

    Lactate dehydrogenase (LDH) is an oxidoreductase found in both eukaryotes and prokaryotes. LDH catalyses the formation of lactate and NAD+ from pyruvate and NADH, during the last step of anaerobic glycolysis. The reaction is also catalysed in the other direction by LDH during the Cori cycle. This reaction can be assayed using spectrophotometric techniques; peak absorbance of NADH is at 340nm, but the peak absorbance of NAD+ is 259nm (Powers, et al., 2007). Enzyme assays are performed to measure the rate of an enzyme-catalysed reaction, known as the enzyme activity.…

    Osmoregulation in Cyclograpsus and Plagusia crab species Hartzer, A.M, 19971613, First year BSc student, Stellenbosch University, South Africa Abstract Osmoregulatory processes within two crab species are investigated in this practical. The Plagusia, an infratidal species, and Cyclograosus, an intertidal species, are investigated to determine which is an osmoregulator and which is an osmoconformer. The haemolymph was extracted after allowing the species to acclimatize to varying concentrations of seawater. The comparative melting-point technique was used in the experiment where capillary tubes were used to collect samples of the seawater and blood, then frozen and put into an alcohol bath.…
