Answer to Question 1

Answer: Ghrelin is released from the stomach when it and the duodenum are empty of food. Injection of ghrelin stimulates eating, while food intake suppresses ghrelin levels.

Answer to Question 2

Answer: Liver cells convert glucose to glycogen, which is then stored within the liver and the muscles. This short-term store is used to fuel the brain and is rapidly depleted. Glucagon secretion catalyzes the conversion of glycogen to glucose. The long-term energy store is within fat cells and is composed of triglycerides. Glycerol is a major product of triglyceride metabolism and is converted to glucose within the liver.
