Where does glycolysis occur in the organ?

Glycolysis occurs in the cytoplasm of all cells in an organ. Regardless of the specific organ (e.g., liver, muscle, brain), glycolysis is a cytosolic process where glucose is metabolized into pyruvate. The subsequent fate of pyruvate depends on the availability of oxygen and the specific energy demands of the organ, either continuing to aerobic respiration in the mitochondria or undergoing fermentation in anaerobic conditions.
