Short Answer Regulation of Blood Sugar
- Due Feb 16 by 11:59pm
- Points 20
- Available Jan 4 at 12am - Feb 16 at 11:59pm
This week's submission will be different. You will not be submitting via Canvas, but rather bringing your work to class the following Wednesday and turning in a hard copy.
Assignment
Create a drawing that shows
- the pathway of a molecule of sugar through your digestive system into your bloodstream (this should include all of the organs and what happens in them) (this is from last week's SA)
- how the pancreas regulates your blood glucose levels in conjunction with the cells of your body and the liver
- make sure to include how the pancreas delivers insulin to the blood stream( exocytosis- vesicles and cytoskeleton), the way glucose enters cells (phospholipid bilayer and GLUT4)
- what are the sugars used for in the liver vs. the cells of the body.
- Make sure to explain about cell respiration and ATP (this from last week's SA)
The drawing should also include what happens if you exercise and BG drops:
- show the role of the pancreas- glucagon is also a protein and you will need the same info about exocytosis
- How does the liver respond? Include information about glycogen and glucose and how the glucose gets out of the liver cells.
Diabetes :
-
-
- On your drawing indicate what the problem is for Type 1 diabetics ( use a different color ink)
- On your drawing, indicate where the problem is for Type 2 Diabetes (use another color)

Blood Glucose Regulation Question 1. After Eating a Meal
After you eat a meal, your blood glucose concentrations begin to rise. Describe what happens in our pancreas/liver negative feedback loop in order to bring us back to homeostasis
Note: you can answer this with a combination of words and a drawing/flow chart

Blood Glucose Regulation: Question 2 After Exercise
As you exercise, you are using a lot of energy. Describe what happens in our pancreas/liver negative feedback loop in order to keep our blood glucose levels normal?
Note: you can answer this with a combination of words and a drawing/flow chart

Causes of Diabetes Question 1 :
Type 1 Diabetes: Which part of the negative feedback loop doesn't work for type 1 diabetics?
How do they treat Type 1 Diabetes? Type 2 Diabetes: Which part of the negative feedback loop doesn't work for type 2 diabetics? How do they treat Type 2 Diabetes? These can be very short answers- ie not even a sentence!
