1,3-bisphosphoglycerate is one of the two phosphoryl group donors in the synthesis of ATP during glycolysis. In human erythrocytes, the steady-state concentration of ATP is 2.24 mM, ADP is 0.25 mm, and 3-phosphoglycerate is 0.12 mm. Calculate the concentration of 1,3-bisphosphoglycerate at 25°C, assuming that the phosphoglycerate kinase reaction) is at equilibrium in the cell. (Standard delta G = -18.9).
