Question

Quizplus · Accepted Answer

Leptin is a hormone produced by fat cells that helps regulate body weight by inhibiting hunger. When leptin levels in the blood are high, the brain receives signals to suppress appetite and increase metabolism to burn stored fat. This is one of the mechanisms by which the body maintains energy balance and prevents excessive weight gain. Insulin regulates blood sugar and metabolism, but does not directly affect appetite. Endorphins and norepinephrine are neurotransmitters that influence mood, pain, and arousal, but do not play a significant role in appetite regulation.
