BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Glucose is stored as glycogen primarily in the cytoplasm of liver and muscle cellular tissue, and in small amounts in brain tissues. While glycogen in the liver acts as the main depot source that maintains blood glucose homeostasis, glycogen in skeletal muscles provides energy to muscles during high-intensity exertion.

Detailed explanation-2: -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-3: -Glycogen functions as one of two forms of energy reserves, glycogen being for short-term and the other form being triglyceride stores in adipose tissue (i.e., body fat) for long-term storage. In humans, glycogen is made and stored primarily in the cells of the liver and skeletal muscle.

Detailed explanation-4: -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.
