Phosphorylation, 2 molecules of ATP release two phosphates which attach to glucose molecule forming hexose bisphosphate.
Lysis, unstable to splits into two triose phosphate molecules.
Phosphorylation, another phosphate group is added to each triose phosphate forming two triose bisphosphate molecules.
The two triose bisphosphate molecules are oxidised by removing hydrogen atoms to form two pyruvate molecules. At the same time ATP molecules are produced removing phosphates from triose bisphosphate during substrate level phosphorylation
