Explanation Justify reason for correct answer: Ghrelin is a peptide hormone, secreted by cells of the gastrointestinal tract (stomach cells). Cells that secrete ghrelin are named ghrelin cells. It takes action on cells of the hypothalamus and increases hunger along with the secretion of gastric acid. Some other cells also synthesize ghrelin, but primarily ghrelin is formed by the stomach. Option (d) is given as stomach. Hence, it is a correct answer. Justify reasons for incorrect answers: Option (a) is given as ‘brain’...

Ghrelin (appetite-stimulating hormone) is a peptide hormone (synthesized from amino acids), which is produced by cells of the gastrointestinal tract. Receptors for the ghrelin are present on brain cells. After binding with its receptors, it increases hunger, secretion of gastric acid and makes the body ready for an uptake of food.
