The overall △G for glycolysis is -72 kJ/mol in erythrocytes. Which statement below is true?
A) The value of △G0ʹ is also -72 kJ/mol since the cytosol pH is close to 7.
B) The free energy of glycolysis is found as the sum of the standard free energy changes for
the individual pathway reactions.
C) The negative sign of △G shows that this pathway will proceed toward product (pyruvate) under normal cellular conditions.
