- B. When blood glucose levels are too high
- C. During fasting
- D. After exercise
Answer
The correct option is When blood glucose levels are too high. This answer is correct because it matches the approved learning objective to explain that insulin causes glucose to move from the blood into cells in the subtopic Control of blood glucose concentration.
Explanation
The correct option is When blood glucose levels are too high. When blood glucose levels are too high is correct because it directly supports the approved learning objective to explain that insulin causes glucose to move from the blood into cells. 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 Insulin's Role
Students often think that insulin directly lowers blood glucose levels instead of understanding that it facilitates the movement of glucose from the blood into cells.
Clarify that insulin acts as a key that allows glucose to enter cells, thereby reducing blood glucose levels indirectly.
