The equation of lactic acid fermentation can be written as: C 6 H 12 O 6 → C 3 H 6 O 3 + energy. Lactic acid can be converted back to pyruvate in well-oxygenated muscle cells; however, during exercise the focus in on maintaining muscle activity. this is the stem that commits the substrate irreversible to the glycolytic pathway, so by controlling the rate of this step the cell can speed up or slow down the entire catabolic process. Lactic acid fermentation in muscles results in the accumulation of lactic acid in the tissues, which leads to sore muscles. fermentation A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid. Lactic acid causes muscle fatigue and they work less efficiently, Once made, lactic acid is transported form the muscles via the blood to the liver, where it is broken down (Oxidise to carbon dioxide and water.
