Question

Quizplus · Accepted Answer

Leptin is a hormone that is produced by fat cells and signals to the brain that the body has had enough food and can stop eating. Animals that lack leptin will not receive this signal and will continue to eat, even when they are physically full. Ghrelin increases appetite, insulin regulates blood sugar levels, estrogen is a sex hormone, and thyroxin regulates metabolism.
