Question

Quizplus · Accepted Answer

Leptin is a hormone produced by adipocytes (fat cells) that helps to regulate body weight and energy balance by suppressing appetite and increasing energy expenditure. Leptin levels increase as fat stores increase and decrease as fat stores decrease. Ghrelin is a hormone produced by the stomach that increases appetite, CCK is a hormone produced by the small intestine that stimulates the release of digestive enzymes and bile, and obestatin is a peptide hormone that may be involved in regulating appetite and energy balance but its role is still unclear.
