BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -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-3: -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. They send the glucose out into the body.

Detailed explanation-4: -In humans, glycogen is made and stored primarily in the cells of the liver and skeletal muscle. In the liver, glycogen can make up 5–6% of the organ’s fresh weight: the liver of an adult, weighing 1.5 kg, can store roughly 100–120 grams of glycogen.

Detailed explanation-5: -Activation from insulin causes the liver and muscle cells to produce an enzyme called glycogen synthase that links chains of glucose together. Delivering glycogen molecules can to the liver, muscles, and fat cells for storage with plentiful glucose and insulin.
