Question

The graph shows the blood-glucose levels and insulin levels of an individual.

Blood-glucose levels are controlled by a feedback loop that involves the hormone insulin. Which of the following statements best explains the role of insulin in this feedback loop?

Insulin controls the blood-glucose level in a positive feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to raise the blood-glucose level even higher.

Insulin controls the blood-glucose level in a negative feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to raise the blood-glucose level even higher.

Insulin controls the blood-glucose level in a positive feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to lower blood-glucose back to the normal level.

Insulin controls the blood-glucose level in a negative feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to lower blood glucose back to the normal level.
