Document Summary
Galactose: glycogen metabolism, fructose metabolism, galactose metabolism. Glycogen is the storage form of glucose in all cells. However, it is especially abundant in liver and muscle. Glycogen is present in cytosol in the form of granules ranging in diameter from 10 to. 40 nm and consists of ~ 55,000 glucose molecules. 1-2% glycogen by weight, 400g glycogen/ 35 kg muscle. 10% glycogen by weight, 100g glycogen/ 1. 6 kg liver. That is, it only depends on the number of solute (e. g. , glucose) molecules. Osmosis is independent of the type or size of the solute molecule. The concentration of glycogen in the liver is . 00001 mm. Therefore you would need 400 mm glucose to match glycogen. Atp to pump glucose into the cell against the concentration gradient. More importantly, water would rush into the cells and cause lysis. Muscle glycogen serves as a fuel reserve for atp synthesis during muscle contraction. Liver glycogen serves as a source of blood glucose.
