Question

Quizplus · Accepted Answer

Leptin is a hormone that is secreted by fat cells in the body and is involved in the regulation of hunger and satiety. When leptin levels are high, it signals to the brain that the body has enough energy stores and can reduce feelings of hunger. Therefore, choice A is the best answer. Choices B, C, and D are incorrect as there is no evidence to suggest that leptin affects sleep or immune system functioning, and it does not cause reduced metabolism.
