Question

Quizplus · Accepted Answer

Leptin and insulin are both involved in long-term regulation of hunger. Leptin is produced by adipose tissue and sends signals to the brain to reduce food intake and increase energy expenditure. Insulin is produced by the pancreas and helps regulate glucose levels in the body, but it also plays a role in appetite regulation by signaling to the brain that the body has enough energy stores. Choice A is incorrect because CCK is involved in short-term regulation of hunger by promoting satiety after a meal. Choice B is incorrect because ghrelin is involved in short-term regulation of hunger by stimulating appetite before a meal. Choice C is also incorrect because PYY is involved in short-term regulation of hunger by promoting satiety after a meal.
