In aerobic cells, however, glycolysis is only the first stage in glucose degradation. The reactions of glycolysis result in the breakdown of glucose into pyruvate, with the net gain of two molecules of ATP (Figure 2.32). The initial ...
WebThe first reaction in glycolysis is the phosphorylation of glucose: P i + glucose → glucose-6-phosphate + H 2 O This is a thermodynamically unfavorable process, with ∆G°′ = +13.8 kJ/mol. (a) In a liver cell at 37 °C the concentrations of both phosphate and glucose are normally maintained at about 5 mM each.
