Question: How do levels of blood glucose fluctuate throughout the day in someone with diabetes compared to someone without diabetes? Materials: Graph Paper Procedure: Compare the following blood glucose concentration data provided for Maria and Tamika. One of these young women has diabetes. Blood glucose concentrations were monitored over 15 hours for both. Both women ate identical meals at the same times, and got equal amounts of exercise at the same times. Neither is currently taking insulin. Plot both sets of data on the same graph. A line graph is recommended. Make sure to label your graph appropriately. Observations: Event/Time Blood Glucose Concentration (mmol/L) Maria Tamika Wake up 8:00 am 4.0 10.0 1 h after breakfast 9:00 am 7.0 14.0 Pre-lunch 12:00 pm 4.5 10.0 2 h after lunch 2:00 pm 6.0 15.0 Mid-afternoon 3:00 pm 4.5 10.0 1 h after vigorous exercise 4:00 pm 4.0 4.0 Pre-supper 6:00 pm 4.5 9.0 1 h after supper 7:00 pm 6.5 18.0 Bedtime 11:00 pm 4.5 12.0

The graph shows the blood-glucose levels and insulin levels of an individual. 50 25 Glucose Insulin 0+ 00 12 16 24 04 08 20 Time (h) Blood-glucose levels are controlled by a feedback loop that involves the hormone insulin. Which of the following statements best explains the role of insulin in this feedback loop? 1.) Insulin controls the blood-glucose level in a positive feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to raise the blood-glucose level even higher. 2.) Insulin controls the blood-glucose level in a negative feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to raise the blood-glucose level even higher. 3.) Insulin controls the blood-glucose level in a positive feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to lower blood-glucose back to the normal level. 4.) Insulin controls the blood-glucose level in a negative feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to lower blood glucose back to the normal level.

When a healthy individual takes a glucose tolerance test, the blood glucose level will spike but then return to normal. In a patient with type 1 diabetes, the blood glucose level will spike dramatically and remain high due to inadequate insulin release. In a patient with type 2 diabetes, the blood glucose level will also spike dramatically and remain high due to a reduced sensitivity to insulin. In Jessie's case, her blood glucose levels were normal throughout the glucose tolerance test, except that she was more hypoglycemic than normal at the beginning and end of the test. Select all the hypotheses that could explain Jessie's glucose tolerance test results. a. Her glucagon levels are too low when she fasts. b. Her glucagon levels are too high when she fasts. c. Her glucose production during fasting is lower than normal due to a problem with gluconeogenesis in the liver. d. Her tissues are taking in more glucose from the blood to compensate for inadequate ATP production, such as from β-oxidation of fatty acids. e. Her blood glucose levels are high because she is diabetic.

People with diabetes measure their fasting plasma glucose (FPG; measured in units of milligrams per milliliter) after fasting for at least 8 hours. Another measurement, made at regular medical checkups, is called HbA. This is roughly the percent of red blood cells that have a glucose molecule attached. It measures average exposure to glucose over a period of several months. The table below gives data on both $\mathrm{HbA}$ and $\mathrm{FPG}$ for 18 diabetics five months after they had completed a diabetes education class. $$\begin{array}{ccc|ccc}\hline \text { Subject } & \begin{array}{c}\text { HbA } \\\text { (\%) }\end{array} & \begin{array}{c}\text { FPG } \\\text { (mg/mL) } \end{array} & \text { Subject } & \begin{array}{c} \text { HbA } \\\text { (\%) }\end{array} & \begin{array}{c}\text { FPG } \\\text { (mg/mL) }\end{array} \\1 & 6.1 & 141 & 10 & 8.7 & 172 \\2 & 6.3 & 158 & 11 & 9.4 & 200 \\3 & 6.4 & 112 & 12 & 10.4 & 271 \\4 & 6.8 & 153 & 13 & 10.6 & 103 \\5 & 7.0 & 134 & 14 & 10.7 & 172 \\6 & 7.1 & 95 & 15 & 10.7 & 359 \\7 & 7.5 & 96 & 16 & 11.2 & 145 \\8 & 7.7 & 78 & 17 & 13.7 & 147 \\9 & 7.9 & 148 & 18 & 19.3 & 255 \\\hline \end{array}$$ (a) Make a scatterplot with HbA as the explanatory variable. Describe what you see. (b) Subject 18 is an outlier in the $x$ direction. What effect do you think this subject has on the correlation? What effect do you think this subject has on the equation of the least-squares regression line? Calculate the correlation and equation of the least-squares regression line with and without this subject to confirm your answer. (c) Subject 15 is an outlier in the $y$ direction. What effect do you think this subject has on the correlation? What effect do you think this subject has on the equation of the least-squares regression line? Calculate the correlation and equation of the least-squares regression line with and without this subject to confirm your answer.
