Glycogen is broken down into glucose through a process called glycogenolysis. This process involves the release of glucose molecules from glycogen stores by the enzyme glycogen phosphorylase. These glucose molecules can then be used by the body for energy production.

Glucose-6-phosphate is important because it serves as an intermediate in glycolysis, providing a starting point for further energy production in the form of ATP. It is also a precursor for the synthesis of nucleotides and amino acids, contributing to various metabolic pathways in the body. Additionally, glucose-6-phosphate plays a crucial role in the pentose phosphate pathway, which generates NADPH for cellular antioxidant defense and biosynthetic processes.

A coupled reaction is when two reactions are linked, and the energy released from one reaction drives the other. In the conversion of glucose to glucose-6-phosphate, the initial phosphorylation of glucose to form glucose-6-phosphate is coupled with the hydrolysis of ATP to ADP. The energy released from ATP hydrolysis drives the phosphorylation of glucose, making the overall reaction thermodynamically favorable.

The formation of glucose 6-phosphate from two molecules of phosphoglyceraldehyde occurs during the second phase of glycolysis, known as the payoff phase. This is achieved through a series of enzymatic reactions that involve the oxidation and rearrangement of the intermediate compounds. Ultimately, the production of glucose 6-phosphate serves as an entry point into further metabolic pathways within the cell.

Liver glycogen can easily produce glucose by glycogenolysis and that can be used by local cells for respiration.

The addition of an inorganic phosphate molecule occurs during the first step of glycolysis, where glucose is phosphorylated to glucose-6-phosphate by the enzyme hexokinase or glucokinase.

NADPH for fatty acid synthesis is primarily generated through the pentose phosphate pathway (PPP). The enzymes glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase in the PPP produce NADPH. Another important source of NADPH is the malic enzyme, which converts malate to pyruvate in the mitochondria, generating NADPH in the process.

Phosphoglucose isomerase is an enzyme that catalyzes the conversion of glucose-6-phosphate to fructose-6-phosphate in the glycolysis pathway. This reaction involves the rearrangement of the carbon skeleton of the glucose molecule, resulting in the formation of fructose, which can then continue to be broken down for energy production.

Glycogenolysis, breakdown of glycogen, produces glucose-6-phosphate, which in liver is further converted to glucose-1-phosphate that can leave the hepatocytes to the blood. This doesn't happen in muscle cells, so the glucose-6-phosphate is used in glycolysis instead during muscle contraction to produce ATP for myosin.
