Glyceraldehyde 3-phosphate is oxidized by NAD+ generates an NADH and G3P to bond w/ an inorganic phosphate. 1,3 Bisphosphoglycerate

Enzyme "Aldolase" cleaves F6-P into two three-carbon molecules(glycolytic pathway)

Enzyme "phosphoglycerate kinase" catalyzes the transfer of one 1,3 BPG to 3-phosphoglycerate. HAPPENING SIMULTANEOUSLY *CREATE 2 ATP's)

Second ATP gives its phosphate to F6-P rendering it Fructose 1,6 bisphosphate, priming it for cleavage *2 ATP MOLECULES HAVE BEEN CONSUMED, second control point*

Pyruvate Kinase enzymatically transfers phosphenolpyruvates phosphate group to a molecule of ADP *GENERATES A MOLECULE OF PYRUVATE AND MOLECULE OF ATP* THIS IS THIRD CONTROL POINT

ATP gives glucose one phosphate, glucose 6-phosphate *First control point:consumes one molecule of ATP*
