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.
D) All of the above
