WebMar 23, 2024 · Aerobic glycolysis and anaerobic glycolysis steps are the same. This mechanism does not need oxygen and, therefore, exists either in the presence or absence of O 2. This cannot be said of the entire cell respiration process where anaerobic and aerobic pathways differ. The glycolysis process is divided into ten steps. Step One: … WebThe glycolytic pathway can be used for the synthesis of glucose from simpler molecules through gluconeogenesis. Gluconeogenesis is the synthesis of glucose from nonsugar sources, especially amino acids and TCA cycle intermediates.
