Answer to Question 1

Answer: The stomach does play a role in satiety in that nutrient sensors are located within the stomach and that removal of a meal from the stomach during a period of satiety will result in the animal consuming sufficient food to replace the withdrawn food.

Answer to Question 2

Answer: CCK is released into blood upon the entry of fats into the duodenum. CCK is thus in a position to provide a satiety cue to the brain. Injection of CCK reduces eating in the short-term. Obesity is noted in rats for which a genetic mutation impairs the production of CCK receptors.
