Question
What role does glucagon play in regulating blood glucose concentration when levels are too low?
Answer
Glucagon is a hormone secreted by the pancreas when blood glucose concentration falls below normal levels. It stimulates the liver to convert stored glycogen into glucose, which is then released into the bloodstream, raising blood glucose levels back to normal.
Explanation
This answer is strong because it clearly defines the function of glucagon and its effect on blood glucose levels, demonstrating an understanding of hormonal regulation in the body. The question tests the student's ability to explain the physiological role of a specific hormone in maintaining homeostasis.
Common mistake
Misunderstanding Glucagon's Role
Students often confuse glucagon with insulin, thinking both hormones function similarly in regulating blood glucose levels.
Remember that glucagon is secreted when blood glucose is too low, stimulating the liver to convert glycogen back into glucose, while insulin is released when blood glucose is too high to facilitate glucose uptake by cells.
