It involves the transfer of phosphate group from the 1, 3-bisphosphoglycerate to ADP by the enzyme phosphoglycerate kinase, thus producing ATP and 3-phosphoglycerate. Since two moles of 1, 3-bisphosphoglycerate are formed from one mole of glucose, two ATPs are generated … Webreaction is the linker between glycolysis and the Krebs cycle and produces acetyl-CoA. Acetyl-CoA can be used in different pathways including the Krebs cycle. In this pathway, one molecule of NADH2 is produced. NADH2 enters the OXPHOS process and releases 3 ATP.
