Question

Insulin in the blood appears to be interpreted by the brain as?

1) a hunger signal
2) an indicator of the entry of fat into the duodenum
3) an indicator that the body is in the absorptive phase of metabolism
4) a satiety signal
5) a signal that the body requires food

Answer 1

Insulin in the blood is interpreted by the brain as a satiety signal.

Step-by-step explanation:

Insulin is interpreted by the brain as a satiety signal. Insulin regulates blood glucose levels and promotes the absorption of glucose by liver hepatocytes, muscle cells/fibers, and adipose cells. It also stimulates the storage of glucose as glycogen and promotes the synthesis of protein in muscle. The signals of hunger and satiety are controlled in the hypothalamus region of the brain, and foods rich in fatty acids tend to promote satiety more than foods rich in carbohydrates.
