- A. Glycogen levels increase.
- B. Glycogen levels remain unchanged.
- C. Glycogen is converted back into glucose.
- D. Glycogen is converted into fat.
Answer
The correct option is Glycogen is converted back into glucose.. This answer is correct because it matches the approved learning objective to explain (HT only) that glucagon causes glycogen to be converted back into glucose in the subtopic Control of blood glucose concentration.
Explanation
The correct option is Glycogen is converted back into glucose.. Glycogen is converted back into glucose. is correct because it directly supports the approved learning objective to explain (HT only) that glucagon causes glycogen to be converted back into glucose. 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 have the same function in blood glucose regulation.
Remember that glucagon's role is to increase blood glucose levels by converting glycogen back into glucose, while insulin lowers blood glucose levels by facilitating glucose uptake into cells.
