The hypothesis being stated was, if the pH of living cells in beef liver is related to the buffer solutions when acids and bases are added, the liver will respond most like the buffers than water. The hypothesis was supported by the data presented in the graph because it demonstrated that the constant pH of liver acted more like the buffers than the wildly changing pH of the tap water. Both buffers stayed relatively at the same pH level with the addition of bases (NaOH) and acids (HCL). Buffer #1 showed a consistent pH of 7 when both the acid and the base were added. Buffer #2 displayed a range of pH from 8-10 when adding HCl drops and remained a constant pH of 10 with the NaOH. Similarly, the beef liver remained at the pH of 7 when mixed with …show more content…
The tap water and NaOH mixture went from the pH of 6 up to a pH of 14. As shown in the graph, the pH of water ranged from 1-14, while the experimental group (liver) stayed constant. When comparing the two groups, they reacted oppositely in terms of pH with the added drops of HCl and NaOH. Some errors that possibly occurred include the pH paper not being as accurate of a source because there is just whole numbers, no in between. The pH number could have also been inexact because it is based on a color scale and every experimenter’s eyes view the colors differently. Additionally, the buffers solution could have not started exactly at a pH of 7 or at a pH of 10. Both buffers in the experiment sustained a steady pH because the role of buffers in our bodies is to regulate the pH and keep it from fluctuating dramatically. Buffers provide us with the ability to aid in homeostasis, the ability of an organism to maintain equilibrium by adjusting physiological process, because the buffer resists a change in pH even as acids and bases are being added. On the other hand,water has a pH of 7, therefore, it is

Potato Catalase Lab

energy of a substrate5. In this lab, hydrogen peroxide is added to six different samples of cells; raw hamburger, spinach leaf, raw liver, boiled liver, chalk and potato. The purpose of the lab is to observe the reaction of Hydrogen Peroxide with catalase in animal and plant cells, to compare the activity of catalase in animal cells and plant cells and to analyses the effects of boiling enzymes. Both animal and plant cells are known to contain catalase1-3,6. The lab will test to see which cells, plant…

Metabolism Research Paper

During the lactase lab people had observed how lactase broke down lactase molecules. This shows how enzymes can be changed to denature and break peptide bonds. During the pineapple lab we saw how using something that increases the breakdown of a solid. during the liver lab we noticed that enzymes can change and denature in different temperatures and pH. when we put the liver in a different pH, it denatured quick just like the hypothesis that was made. also in that lab we saw how temperature can…

Acute Hepatitis B Essay

examination, it is noted that the skin is jaundiced and the liver enlarged. D.W. denies significant alcohol or drug use. He denies any known exposure to hepatitis and has never been vaccinated for hepatitis. He is taking no medication. Laboratory tests reveal the following and a diagnosis of acute hepatitis B is made: 1. Review and analyze the laboratory data. What diagnosis is supported by these values? Give your rationale. Mr. Wilson’s lab work is reviewed below: * AST 142 IU/L *…

Biology Enzyme Lab Essay

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1,000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)…

Lab Report Essay

was: If the liver solution is related to the buffers, then the liver solution’s pH level when mixed with HCl and NaOH will stay the same. Our hypothesis was refuted by the data showed in this lab because the pH level of the liver solution did not stay the same like the buffers did. The control groups found in this lab were buffer one and buffer two mixed with HCl and NaOH because there was no increase or decrease in the change of pH levels. There was a slight increase of pH in the liver solution when…

Statin Induced Rhabdomyolysis Summary

It was these lab results that helped lead the doctors to a diagnosis of statin-induced rhabdomyolysis. While some the lab tests resulted in measurements outside of the normal range, others did not indicate a problem and these latter tests were equally important in reaching a diagnosis. Sodium – The sodium levels…

Acid Base Lab

In this experiment, the hypothesis if acid(HCI) or base(NaOH) is added to a biological solution(liver), then the pH of the liver solution will respond more like a buffer was tested. This hypothesis is supported by the data collected in the experiment. The liver when either the acid or base was added acted like that of a buffer not distilled water. The buffer tested in this lab when the NaOH was added started out at around 9.95 pH and gradually increased an average of .04 every drop until around 10…

Enzyme Lab Experiment: Test Tube Essay examples

SBI 4U: Enzyme Lab Sonia Pereira March 6 2013 Ms. Farrell Lab Partner: Danielle Luciani Sources of Error: As the liver for the experiment in test tube C was cooked by the teacher, we had no control over the duration it was cooked at effecting it’s effervescence when placed in the test tube containing hydrogen peroxide. If the liver was over cooked the extreme heat would denature the catalyze enzymes in the meat resulting in little…

Liver Transplant Essay

Liver Transplant A liver transplant is a last resort! (Sorry, you don’t get a liver just because you don’t feel good) Once your liver has become decompensated (unstable), you will most likely experience following symptoms on more than one occasion: Ascites, Hepatic Encephalolpathy, and/or Esophageal Varices UNOS uses 3 lab results that determine your MELD. Your INR, your Creatine level, and your bilirubin. Your INR calculates how fast your blood clots. Your Creatine calculates your kidney…

decreased cardiac output, decreased nutritional intake, and subsequent acute kidney damage-- which decreased reuptake r/t the renal tubules, would have caused the low total protein levels in the patient’s blood. The inflammation from his kidneys and his liver would also contribute to this issue. The patient’s position when the blood sample was taken would affect total protein levels because if he were supine then he would indicate lower levels of protein than if he were in a standing position. (Leeuwen…
