The energy released by this highly exergonic oxidation reaction drives the endergonic second reaction (ΔG°'=+50 kJ/mol (+12kcal/mol)), in which a molecule of inorganic phosphate is transferred to the GAP intermediate to form a product with high phosphoryl-transfer potential: 1,3-bisphosphoglycerate (1,3-BPG).
A enerxía liberada por esta reacción de oxidación moi exergónica impulsa a segunda reacción, que é endergónica (ΔG°'=+50 kJ/mol (+12kcal/mol)), na cal se tranfire unha molécula de fosfato inorgánico ao intermediato GAP para formar un produto cun alto potencial de transferencia do fosforilo, o 1,3-bisfosfoglicerato (1,3-BPG).
