Quizplus · Accepted Answer

Leptin is a hormone produced by adipose tissue (fat cells) that signals the brain to decrease appetite and increase feelings of fullness. Its release into the bloodstream is triggered by an increase in fat stores. Polypeptide Y (A) is a hormone that increases appetite and promotes food intake. Insulin (B) is a hormone that regulates blood sugar levels by promoting the uptake of glucose into cells, but it does not directly affect appetite. Glucose (D) is a type of sugar and fuel for the body, not a hormone that affects appetite.
