Fig. 14-16 Metabolic Fates of Pyruvate 1. Aerobic conditions: completely oxidized to CO 2 and H 2 O via the citric acid cycle 2. Anaerobic conditions in muscle: reduced to lactate 3. Anaerobic conditions in yeast: ethanol + CO 2

Homolactic Fermentation • Occurs in muscle, particularly during vigorous activity when: - High demand for ATP - Short supply of oxygen Glucose + 2 ADP + 2 P i 2 lactate + 2 ATP + 2 H 2 O + 2 H + • Muscle fatigue and soreness is caused by low pH, not by lactate. Muscle can work long if the pH is kept constant • Overall process of anaerobic glycolysis
