AP PSYCHOLOGY

Detailed explanation-1: -Leptin is a hormone released from fat cells in adipose tissue. Leptin signals to the brain, in particular to an area called the hypothalamus. Leptin does not affect food intake from meal to meal but, instead, acts to alter food intake and control energy expenditure over the long term.

Detailed explanation-2: -The hormone leptin is produced by fat cells and is secreted into our bloodstream.

Detailed explanation-3: -Leptin also supports efficient metabolism. Its role in weight loss, weight gain, and obesity has been studied in animals and humans. Leptin travels through your blood, via your circulatory system, to the appetite center of your brain. There, it binds to receptors that are responsible for making you feel hungry.

Detailed explanation-4: -Leptin is secreted by fat cells (adipocytes), and was originally thought to signal to the brain to inhibit food intake and decrease weight (2, 5).

Detailed explanation-5: -Ghrelin is a multifaceted gut hormone which activates its receptor, growth hormone secretagogue receptor (GHS-R). Ghrelin’s hallmark functions are its stimulatory effects on food intake, fat deposition and growth hormone release. Ghrelin is famously known as the “hunger hormone”.
