Glycogenolysis

Glycogenolysis occurs in muscle and liver tissue cells in response to hormonal and neural signals. It provides energy (ATP !) And plays an important role in regulating glucose levels in the blood. Under anaerobic conditions it produces lactic acid (cramps!), otherwise AcetylCoA which is metabolized in the Krebs cycle.
