LABORATORY REPORT Activity 5: Blood Glucose Regulation Name: Instructor: Date: MATERIALS AND METHODS 1. Dependent Variable Plasma levels of glucose, ketones, insulin, and glucagon 2. Independent Variable Food and beverage intake 3. Controlled Variable physical activity, caffeine and alcohol intake, gender, age BMI 4. Why were physical activity and caffeine and alcohol intake the controlled variables? Because you can control on the amount of time you spend doing physical activities and the intake of both caffeine and alcohol. 5. What type of assay was used to measure plasma glucose and ketone levels? glucose, oxidase, peroxide, dianisidine 6. What type of assay was used to measure plasma…show more content…
When was plasma insulin/glucagon concentration highest? If values are similar for several time points, then give range of times when plasma insulin/glucagon concentration was highest. Insulin was highest 1 hour post meal and glucagon was highest 3 hr post meal 6. When was plasma insulin/glucagon concentration lowest? If values are similar for several time points, then give range of times when plasma insulin/glucagon concentration was lowest Insulin was lowest during fasting snf glucagon was lowest 1 hour post meal DISCUSSION 1. Explain how insulin changed plasma glucose concentration over the course of the experiment. The insulin changed the plasma glucose levels by raising dramatically from fasting to the one hour mark, but by hour 3 it droped again to almost the same levels as fasting. The glucagon remained almost the same on throughout the levels except that it lowered a bit 1 hour after the meal. 2. Explain how glucagon changed plasma glucose concentration over the course of the experiment. Glucagon acts on liver cells to promote breakdown of glycogen into glucose and formation of glucose from lactic acid and certain amino acids. 3. Explain what caused the change in plasma ketone concentration over the course of the experiment. Ketones changed from high during
