Question

Which of the following chemical messengers induces the sensation of feeling full (satiety effect)?
A) somatostatin
B) acetylcholine
C) glucagon
D) epinephrine
E) insulin

Accepted Answer

Insulin, a hormone produced by the pancreas, plays a key role in the regulation of blood glucose levels and has effects on the brain that promote feelings of satiety or fullness. When insulin levels rise after eating, it signals the body that enough food has been consumed, thereby contributing to the sensation of being full.
