A key step in the biosynthesis of triglycerides (fats) is the conversion of glycerol to glycerol-1- phosphate by ATP: Mg2+ Glyserol (G) + ATP glyserol-1-phosphate (G-1-P) + ADP a-glycerol kinase At a steady state in the living cell, (ATP) = 10³M and (ADP) = 104 M. The maximum (equilibrium) value of the ratio (glycerol-1-P)/(glycerol) is observed to be 770 at 25 °C and pH=7. a. Calculate K and A‚G° for the reaction. b.
