Question

glocogen granule function​

Answer 1

Answer:

Glycogen is synthesized from glucose when blood glucose levels are high and serves as a ready source of glucose for tissues throughout the body when blood glucose levels decline.

Functions of Glycogen

1. Liver glycogen acts as a glucose reserve that hepatocyte releases when there is a need to maintain normal blood sugar levels. There is about 40 kcal in body fluids while hepatic glycogen can provide about 600 kcal after a fasting night.
2. Glucose from glycogen stores remains within the cells in skeletal and cardiac muscles and is used as an energy source from muscle work.
3. The brain includes a small amount of glycogen in astrocytes. It gets accumulated during sleep and is mobilized upon walking. Glycogen reserves also assure a moderate degree of protection against hypoglycemia.
4. It has a specialized role in fetal lung type II pulmonary cells. These cells start to accumulate glycogen at about 26 weeks of gestation and then synthesize pulmonary surfactant.
