The mixture of the metabolic intermediates was exposed for 5 h at 40–90°C in 10°C steps, and pyruvate formation monitored by LC‐SRM. Moreover, the Archean ocean mimetic increased the stability of the phosphorylated intermediates and accelerated the rate of intermediate reactions and pyruvate production. Every SRM measurement targeted the full spectra of glycolytic and the PPP metabolites. We report that the resultant reaction milieu catalyses the interconversion of metabolites that in modern organisms constitute glycolysis and the pentose phosphate pathway. The phosphate group attached to the 2′ carbon of the PEP is transferred to a molecule of ADP, yielding ATP. Non‐enzymatic glycolysis and pentose phosphate pathway‐like reactions in a plausible Archean ocean. Glycolysis: The Reactions-- Movie Narrative. The sixth step in glycolysis (Figure 9.1.2) oxidizes the sugar (glyceraldehyde-3-phosphate), extracting high-energy electrons, which are picked up by the electron carrier NAD +, producing NADH. First half of glycolysis: Energy Investment Phase. The fermentation of glucose through the glycolytic pathway can be divided into two stages, each requiring several independent enzymatic reactions. The enzyme phosphoglycerokinase transfers a phosphate from BPG to a molecule of ADP to form ATP. Life (Basel).  |  Nearly all living organisms carry out glycolysis as part of their metabolism.
