Question

Quizplus · Accepted Answer

Leptin is a hormone that is secreted by adipose (fat) cells and helps to regulate appetite by signaling to the brain when the body has enough energy stores. When leptin levels are high, it indicates to the brain that the body has enough energy and can therefore reduce appetite. On the other hand, when leptin levels are low, it indicates that the body needs more energy and can increase appetite to encourage food intake.
