Synthesis of glutamine in living systems, by the process glutamate + NH4*→ glutamine for which AG is 15.7 kJ/mol at 37°C (standard state, 1 mol/dm3) a. Calculate the equilibrium constant for the reaction b. Another reaction is the hydrolysis of adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and phosphate (P) for which the AG value maybe taken as - 31.0 kJ/mol. ATP → ADP + P Since these 2 reactants have no reactant or product in common, they can only be coupled together by a catalyst. The enzyme glutamine synthetase in fact catalyzes the reaction and therefore, couples the reaction together. glutamate + NH4+ + ATP → glutamine + ADP + P Calculate the equilibrium constant for this combined reaction.
