Calculate the equilibrium constant of the reaction in which glutamine is formed -O2CCH (NH3 +) CH2CH2CONH2 (hereinafter G) from glutamic acid -O2CCH (NH3 +) CH2CH2COOH (G ') in cells, under the action of the synthetase enzyme glutamine. This reaction is used to carry ammonia from the cells to the kidneys, where it is re-released and excreted. Use the value of the standard free reaction enthalpy G '(aq) + NH3 (aq) → G (aq) equal to +15.7 kJ / mol at 37 ° C. The reaction is driven by the feed-back of the ATP (aq) → reaction ADP (aq) + Pi (aq). the standard free enthalpy of which is -31 kJ / mol. What is constant equilibrium joint reaction: G '(aq) + NH3 (aq) + ATP (aq) → G (aq) + ADP (aq) + Pi (aq)?
