Question

Quizplus · Accepted Answer

During the fasting phase, glycogen stores are depleted, and the body begins to break down fats to produce energy, a process called lipolysis. This releases fatty acids and glycerol which are used by the liver to produce ketone bodies as an alternative fuel source for the brain and other tissues. Hormones such as gastrin and cholecystokinin stimulate the digestive system, and the release of insulin by the pancreatic β-cells occurs during the fed state when glucose levels are high. The production of glycogen occurs during the fed state when glucose levels are high, and excess glucose is stored in the liver and muscles as glycogen.
