Case 2 – Homeostasis The hormone insulin enhances the transport of glucose from the blood into most of the body's cells. Its secretion is controlled by a negative feedback system between the concentration of glucose in the blood and the insulin secreting cells. Barbara is a pre-diabetic, and monitors her blood sugar every day under various conditions. 1. What would a decrease in blood glucose concentration stimulate to occur in the pancreas? What would be the result in blood glucose concentration? 2. What would an increase in blood glucose concentration stimulate to occur in the pancreas? What would be the result in blood glucose concentration? 3. Name two additional hormones (other than insulin) involved in maintaining normal blood sugar levels.

Step 1
A decrease in blood glucose concentration would stimulate the pancreas to release glucagon. As a result, the blood glucose concentration would increase. $$\text{Decreased blood glucose} \Rightarrow \text{Release of glucagon} \Rightarrow \text{Increased blood Show more…

In organisms, homeostasis of various bodily processes, such as body temperature, blood glucose levels, and blood calcium levels, is essential for the maintenance of proper body functions. What role does insulin play in homeostasis? a. When a fetus pushes against the uterine wall, insulin is released by the brain to stimulate uterine contractions. b. In the presence of decreased blood glucose levels, insulin is produced by the parathyroid to increase calcium absorption. c. Insulin activation activates other clotting factors until a fibrin clot is produced. d. Insulin is secreted by the pancreas in response to elevated blood glucose levels to remove glucose from the blood.
When the body's glucose level rises, the pancreas secretes insulin and, as a result, the blood glucose level declines. When the blood glucose level is too low, the pancreas secretes glucagon and, as a result, the blood glucose level rises. Such regulation of blood glucose level is the result of: cellular respiration negative feedback mechanisms positive feedback mechanisms emergent properties

Increased blood glucagon causes blood glucose levels to rise. Which of the following contributes to this? Choose One A.) Fructose 1,6-bisphosphatase is inhibited. B.) Fructose 2,6-bisphosphate levels increase. C.) PFK-2 is inactivated. D.) Glycogen phosphorylase is dephosphorylated. E.) PFK-1 activity is increased. Which of the following statements regarding insulin is FALSE? Choose One A.) Insulin stimulates the liver to store fatty acids as triacylglycerols. B.) Insulin signals the fed state. C.) Insulin works through activating phosphatases. D.) Insulin results in a lowering of the blood glucose levels.
