Glucose 6-phosphateis rearranged to formits isomer, fructose6-phosphate.

A second ATPtransfers a phosphateto create fructose1,6-bisphosphate.
The fructose ring opens,and the 6-carbon fructose1,6-bisphosphate breaksinto the 3-carbon sugarphosphate DAP and itsisomer G3P.

The DAP moleculeis rearranged to formanother G3P molecule.

The two moleculesof G3P gain phosphategroups and are oxidized,forming two moleculesof NADH + H+ and twomolecules of1,3-bisphosphoglycerate(BPG).

The two molecules ofBPG transfer phosphategroups to ADP, formingtwo ATPs and two moleculesof 3-phosphoglycerate (3PG).

The phosphate groupson the two 3PGs move,forming two 2-phospho-glycerates (2PG).

The two molecules of2PG lose water, becomingtwo high-energy phospho-enolpyruvates (PEP).

Finally, the two PEPstransfer their phosphatesto ADP, forming two ATPsand two molecules ofpyruvate.
