Describe the roles of leptin, ghrelin, and peptide YY in regulating appetite
What will be an ideal response?
Answer: Ghrelin is an appetite-stimulating hormone that is released by gastric cells when the stomach is empty. In contrast, peptide YY is released by enteroendocrine cells to inhibit hunger when the colon is full. Both have short-term effects, whereas leptin, secreted by white adipose tissue, serves as a long-term suppressor of appetite based on the body's fat stores.
