With these solutions, the students were able to test whether not the amylase continues to break down starch with the presence of the carb cutter. Amylase mimics the enzyme activity that occurs in the body upon starch. The carb-cutter acts as the diet pills. The I2KI was used to add color to the solution. It binds with starch so the more starch, the darker the solution was.
Use a new glucose strip and record Data: Conclusion: According to my data, pH levels do, in fact, affect the results of Lactex. I say this because in my experiment, pre-enzyme, my solutions were all negative except for the soda. I used the test strips to determine if they were negative or positive solutions. After I put in the enzyme, Lactex, my results changed. Vinegar, Antacid, and Soap all became positive solutions after I put in the enzyme.
Hypothesis: I think the mass of the egg that is in the water will stay the same but the mass of the egg that is in the sugar will increase mass. Variables: The manipulated variables are the water and the sugar and the responding variable is the mass of the egg. Directions: 1. Soak two eggs in vinegar for one day. 2.
Caffeine & Alcohol Effect on the Water Flea Heart Rate Abstract In this study, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine and alcohol on heart rate. There was a control group used along with the alcohol and caffeine to ensure the results were more accurate. The prediction was the introduction of alcohol and each increased concentration of alcohol, would decrease heart rate and the introduction and subsequent increased concentrations of caffeine would increase heart rate. The results of this experiment proved the prediction to be correct with the alcohol, but the results from the caffeine were hardly noticeable. Methods & Materials
affect the enzyme activity, to get enzymes working there should be proper ph. to avoid denaturing of enzymes, changes in pH alters ionization of charged amino acids. In an experiment to determine the pH range over which the enzyme catechol oxidase is able to catalyze its substrate, this will also help determine the optimum pH in which enzymes work best. Materials • 7 test tubes • Test tube rack • Metric ruler • China marker • Wash bottle containing 1%
5. How does the Mediterranean Diet influence your blood-lipid profile? By replacing some carbohydrate calories with olive oil calories, you can lower your triglyceride levels and maintain or even raise your HDL levels even before you lose a pound. 6. What is Syndrome X or Metabolic Syndrome and what are its characteristics?
INTRODUCTION AIM: The aim of this investigation is to determine and analyse the effects of temperature and light exposure on Vitamin C concentration of a sample orange juice solution by means of volumetric analysis in conducting colorimetric titration testing. HYPOTHESIS: It is predicted that exposure of juice solutions to elevated temperatures and concentrated ultra-violet light rays, will result in increased levels of degradation of Vitamin-C due to oxidation and thus decreased concentrations of Vitamin-C in comparison to control orange juice solutions unaffected by these independent variables. BACKGROUND INFORMATION: Vitamin C, scientifically identified as L-ascorbic acid (information on the enantiomers of ascorbic acid is provided in Appendix ___),is an essential nutrient for normal growth and development of the human body and many animals. It works as a co factor for enzymes essential for synthesis of collagen proteins and also assists the body in the process of healing wound, the maintenance of bones and teeth, and important processes involving ligaments, cartilage, tendons and blood vessels. Vitamin-C is unable to be stored (due to its water solubility) or synthesized by the human body and therefore must be acquired from dietary sources; primarily citrus fruits and vegetables.
Eosin methylene blue and Mannitol agar plates will also be used to determine pH values. Test Three: Gram Stain – A basic technique which will help to distinguish between a Gram-positive and Gram-negative bacterium. Test Four: Catalase assay – Is to be used to determine whether the unknown bacteria will liberate free O₂ gas. Test Five: Oxidase assay – The cytochrome Oxidase will aid in determining whether the unknown bacteria has an absence of Oxidase or not. Test Six: Glucose assay – Whether an organism can respire or ferment glucose can be tested with this Glucose O/F medium assay.
Analysis: My conclusion, that the change in enzymes will affect the amount of apple juice produced because each enzyme will work differently with the apple sauce, can be proved with the data from this experiment. It can be proved because when the enzyme was changed different amounts of apple juice were produced. An example of this could be the pectinase and cellulase solutions. When the cellulase was added to the apple sauce it produced only 1 mL of apple juice, but when the pectinase was added to the apple sauce it produced 4.5 mL of apple juice. That is a change of 3.5 mL from one enzyme to another.
If Eugene’s blood PH is really low than administering sodium bicarbonate (NaHCO3) will help him get back to the range of 7.35 - 7.45. The NaHCO3 will act as a buffer by mixing with acids in his body and then reduce the acid-base imbalance. Since Eugene is a chronic alcoholic I would also run a kidney liver function test to check his enzyme levels, because a if they kidney or the liver is failing then it is not removing the toxins in the body and that will cause a buildup of toxins in the blood stream, resulting in brain
