Question

Quizplus · Accepted Answer

ob/ob mice have a mutation in the gene encoding for leptin, a hormone produced by adipose tissue that regulates appetite and metabolism. Therefore, choice C, leptin, is the correct answer. Choices A, B, and D are not directly related to the ob/ob phenotype. CCK is produced by the small intestine and stimulates the release of pancreatic enzymes and bile. Neuropeptide Y is a neurotransmitter that stimulates appetite, and ghrelin is a hormone that stimulates hunger and food intake.
