Explanation: Lactic acid is formed in the muscle from the carbohydrates metabolism in the cells. When muscles work hard (such as during the time of exercise), the ament of O2 needed is used for consumption during energy production. Thus O lacks in the muscles. This results in another process, anaerobic metabolism. The process of a product obtaining the energy anaerobically is lactic acid, which is built up in muscles that cause pain. Lactic acid, however, helps in the actual healing process.
