Hormonal coordination in humans
Question
- A. By stimulating insulin production
- B. By promoting glucose uptake in cells
- C. By converting glycogen to glucose
- D. By increasing fat storage
Answer
The correct option is By converting glycogen to glucose. This answer is correct because it matches the approved learning objective to explain (HT only) that glucagon is secreted by the pancreas when blood glucose concentration is too low in the subtopic Control of blood glucose concentration.
Explanation
The correct option is By converting glycogen to glucose. By converting glycogen to glucose is correct because it directly supports the approved learning objective to explain (HT only) that glucagon is secreted by the pancreas when blood glucose concentration is too low. This belongs to the subtopic Control of blood glucose concentration within Hormonal coordination in humans, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Control of blood glucose concentration.
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.
