1 Name: Introduction Diabetes is a malfunction of one of the major homeostatic mechanisms in the body the endocrine system. Two hormones, insulin and glucagon control the level of sugar in the blood. The more glucose in the blood and surrounding fluid, the greater the amount of insulin that gets produced. The insulin is produced and released by the pancreas and is used to lower the level of glucose in the blood. This is done by causing cells to uptake (remove) glucose from the blood. If insulin levels fall and blood sugar level becomes too high, glucose in the nephrons cannot be completely reabsorbed by the cells of your body, so glucose is released in the urine. One of the earliest tests for diagnosing diabetes was to taste the urine of a potential diabetic. If it was sweet, diabetes was a probable diagnosis. In this investigation you will observe data taken from various solutions to determine if the glucose levels are high. Benedict s solution is a reagent that changes colour in the presence of glucose. Copper ions within the reagent react with glucose molecules and form cuprous oxide. Cuprous oxide gives a colour change from green to yellow to red depending on the amount of glucose present in a sample. Pre-Lab Questions: 1. What are the steps involved in balancing blood sugar in the body? 2. How does Benedict s solution work to detect sugar? Page 1 of 7
2 Problem: How can you use different indicators to test for blood sugar in a solution (urine)? Prediction: Predict how you can tell if sugar is present in a solution (urine). Materials: 4 samples of solution, labeled A, B. C, and D. 10 ml graduated cylinder 5 test tubes grease pencil test tube rack beaker clamp test tube clamp Benedict s solution 500 ml beaker hot plate medicine dropper Procedure: As per text book, McGraw-Hill Ryerson, pp Page 2 of 7
3 Results: Use Table 1 to determine the glucose level in your sample. Solution Colour Approximate glucose concentration (percentage of solution) Blue Negative Light green 0.15% - 0.5% Olive green 0.5% - 1.0% Yellow-green to green 1.0% - 1.5% Orange 1.5% - 2.0% Red brown 2.0% and greater Table 1: Percentage of glucose in solution Page 3 of 7
4 Figure 1: Sample Solutions Analysis Questions: 1. What were the sugar concentrations for each of the samples in figure 1? Page 4 of 7
5 2. Describe the chemical reaction that was responsible for changing the colour of the Benedict s solution on the test samples. 3. Was this a controlled experiment? Explain your answer. 4. What other controls could be added to the procedure? Page 5 of 7
6 5. One of the symptoms of diabetes mellitus is frequent and copious urination. Explain why this occurs. 6. When we eat a meal. Our blood sugar level rises. How is homeostasis maintained in non-diabetic patients? How do diabetic patients deal with the increase in blood sugar? 7. What other test would need to be performed to conclusively diagnose an individual with diabetes? Would these tests be adequate? Page 6 of 7
7 8. Diabetes mellitus is also called Type 1 diabetes. Another form of diabetes, Type 2 diabetes or adult onset diabetes is more common. Describe the difference between Type 1 and Type 2 diabetes. 9. Explain why Type 2 diabetes can be controlled with lifestyle modification, but Type 1 diabetes cannot. Conclusion: Page 7 of 7
