After reading the information and watching the videos on Diabetes complete the following questions. Remember to use complete sentences where necessary.

1. Discuss how Type 1 Diabetes and Type 2 Diabetes are similar and how they are different (3-4 sentences). DO NOT cut and paste – use your own words.

2. According to the video Diabetes and the body what are some of the symptoms of diabetes?

3. What organ produces insulin?

4. Is there an optimal level of glucose in the body? If there is, what is the range?

In today's exercise, we will investigate the relationship between the pancreas, insulin and carbohydrates. We will investigate the change in blood sugar levels associated with the ingestion of a candy bar. In addition, other experimental data is given for your review and hopefully will provide you with insight and understanding of blood sugar values.

a. Using the graph below, determine the subjects’ pretest (0 hour) blood glucose values and record them in the chart which you will find after the graph.

b. The subjects have been given large candy bars which were ingested quickly (less than 2 minutes).

c. The subjects’ blood glucose levels were tested again at 1, 2, 3, 4, 5, and 6 hours after they ate their candy bars. Record each subjects’ numbers.

d. Complete the related questions following the chart to aid in your understanding of the exercise.

1. Fill in the chart by looking at the graph above:

2. Explain their results. Which ones are normal, hypoglycemic, mildly diabetic, severely diabetic, or other?

3. Which of the above individuals exhibit levels above normal?

4. Which of the above individuals exhibit levels below normal?

5. Were all the pre-ingestion results normal? Who, if anyone, was not normal and why?

6. Did each person’s blood sugar rise immediately after they ate the candy? Explain what we saw happen.

7. Had each person’s level begun to drop by the end of the exercise? Why or why not?

8. Were all the student subject responses within normal parameters? Why or why not?

9. Complete the following chart:

10. What do the hormones in the above chart have in common?

11. Prepare a short story (1-2 paragraphs) which will outline the relationship of the following: aerobic respiration, blood, food, glucocorticoids, glucose, glycogen, homeostasis, hormone, liver, pancreas, small intestine. Make sure to use all 11 words and underline each one. Use your own words for this story.
