3. 1,3-bisphosphglycerate has a high energy bond that can be used to phosphorylate ADP tomake 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 isneeded relative to 3-phosphoglycerateto keep this formation of ATP spontaneous?-203PO.H--OH-OPO3-²+ ADPH--OH-OPO3-²+ ATP
