WebApr 14, 2024 · An established hallmark of cancer cells involves their reliance on glycolysis to generate energy even in the presence of oxygen, otherwise called the Warburg effect [13,14,15]. WebThe standard free energy for this reaction is extremely unfavorable - ΔGo = +23.8 kJ/mol! But the Gibbs free energy is actually favorable, ΔG = -6 kJ/mol. Is this reaction spontaneous? How is the concentration of G-3-P reduced to insure that the aldolase reaction is spontaneous? This completes the “first stage” of glycolysis.
