HUMAN NUTRITION

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: -The capacity of your body to store muscle and liver glycogen, however, is limited to approximately 1, 800 to 2, 000 calories worth of energy, or enough fuel for 90 to 120 minutes of continuous, vigorous activity.

Detailed explanation-3: -Glycogen is the storage form of carbohydrates in mammals. In humans the majority of glycogen is stored in skeletal muscles (∼500 g) and the liver (∼100 g). Food is supplied in larger meals, but the blood glucose concentration has to be kept within narrow limits to survive and stay healthy.

Detailed explanation-4: -Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose. They send the glucose out into the body.
