WebIn aerobic respiration both glycolysis and the Krebs cycle are involved whereas in anaerobic respiration only glycolysis takes place. The flow diagram shows that every time a stage produces two hydrogen atoms, in the presence of oxygen, three ATP molecules are produced. The role of these hydrogen atoms is shown in the electron carrier system. WebGlycolysis consists of 10 stages, each of which involves a different chemical reaction. The stages of glycolysis include: Phosphorylation of glucose. Isomerization of glucose-6-phosphate. Phosphorylation of fructose-6-phosphate. Cleavage of fructose-1,6-bisphosphate.
