The reaction converting glycerol to glycerol-3-phosphate is energetically unfavorable by 9.2kJ. The reaction of ATP with water to yield ADP, hydrogen phosphate ion, and hydrogen ion is energetically favorable by 30.5kJ. These reactions are coupled so that the overall process is energetically favorable.
What is Delta G for the overall process?
energetically favorable: G=-30.5kj
-------------unfavorable: G= 9.2kj
delta G by coupling both equa.= 30.5+9.2= -21.3
