3. 1,3-bisphosphglycerate has a high energy bond that can be used to phosphorylate ADP to make ATP according to the equation below. The free energy of hydrolysis of 1,3- bisphophoglycerate and ATP under standard conditions are -49.4 kJ/mol and -30.5 kJ/mol, respectively. If the [ATP] to [ADP] is about 4 in the cell, how much 1,3-bisphophoglycerate is needed relative to 3-phosphoglycerate to keep this formation of ATP spontaneous? -203PO.
