An important biochemical reaction that is used to do work (on muscle, or in transport of chemical species, or in driving biosynthesis) involves AdenosineTriPhosphate (ATP) and AdenosineDiPhosphate (ADP) and can be written as: ATP + H2O → ADP + Pi + H+ AG° = +9.2 kJ where Pi" is inorganic phosphate. In biological systems this reaction is, to an excellent appoximation, carried out at constant pressure (1 atm) and constant temperature. Is this reaction spontaneous when carried out with all reactants and products present at standard state thermodynamic conditions? O yes, it is spontaneous with all reactants and products present at standard state thermodynamic conditions O no, it is not spontaneous with all reactants and products present at standard state thermodynamic conditions - it is spontaneous in the reverse direction O It is at equilibrium when all reactants and products are present at standard state thermodynamic conditions the information given is not sufficient to answer the question
Calculate AG (in J) for the ATP-ADP reaction of Question 3 at 25°C and the typical physiological conditions: pH = 7.3 Molarity of ATP = 0.006 M Molarity of ADP = 0.924 M Molarity of Pi- = 0.282 M
