Detailed explanation-1: -Glycolysis occurs in both aerobic and anaerobic states. In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the net production of 32 ATP molecules. In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis.
Detailed explanation-2: -The reference sources assert that glycolysis produces pyruvic acid (i.e., pyruvate and protons), and that under anaerobic conditions, glycolysis produces lactic acid.
Detailed explanation-3: -The anaerobic glycolytic process results in Pyruvate binding with some of the hydrogen ions and converting them into a substance called lactate (completely different to ‘lactic acid’).
Detailed explanation-4: -Glycolysis is used by all cells in the body for energy generation. The final product of glycolysis is pyruvate in aerobic settings and lactate in anaerobic conditions.
Detailed explanation-5: -Lactic acid fermentation is the type of anaerobic respiration carried out by yogurt bacteria (Lactobacillus and others) and by your own muscle cells when you work them hard and fast. Figure 15.3.
