Leptin is to Satiety as ________ is to Hunger

Question

Leptin is to satiety as ________ is to hunger.
A) Gastrin
B) Pepsin
C) Ghrelin
D) Cholecystokinin
E) Secretin

Accepted Answer

Ghrelin is commonly known as the "hunger hormone" because it increases appetite and food intake. It is released in the stomach and signals the hypothalamus to stimulate hunger when the stomach is empty. Leptin, on the other hand, decreases appetite and stimulates the feeling of fullness or satiety. Gastrin, Pepsin, Cholecystokinin, and Secretin are not directly related to hunger or appetite control.
