Glycolysis is an oxygen independent metabolic pathway, meaning that it does not use molecular oxygen (i.e. atmospheric oxygen) for any of its reactions. However the products of glycolysis (pyruvate and NADH + H+) are sometimes disposed of using atmospheric oxygen.
catabolic pathway in which stored glycogen is broken down to its constituent glucose molecules, either for immediate oxidation for energy, or for transport out of the cell into the blood in order to maintain blood glucose levels. This pathway is stimulated by glucagon.
