Detailed explanation-1: -Glucose is the main source of fuel for our cells. When the body doesn’t need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen.

Detailed explanation-2: -After meals, glucose is stored as glycogen in the liver. During fasting periods, glucose is released from glycogen (glycogenolysis) becoming available to be used in other tissues.

Detailed explanation-3: -Our body stores excess glucose as glycogen (a polymer of glucose), which becomes liberated in times of fasting. Glucose is also derivable from products of fat and protein break-down through the process of gluconeogenesis.

Detailed explanation-4: -Glycogen is a main source of energy for the body. Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose.

Detailed explanation-5: -Your body mainly uses the store of glycogen in your liver to help regulate your blood glucose (sugar) levels. Your body normally carefully regulates your blood glucose primarily with the hormones glucagon and insulin. When your blood glucose levels fall too low (hypoglycemia), your pancreas releases more glucagon.
