The following reactions can be coupled to give alanine andoxaloacetate: glutamate + pyruvate â†” ketoglutarate + alanine âˆ†Goâ€™rxn,303 = âˆ’ 1004 J/mol glutamate + oxaloacetate â†” ketoglutarate +aspartate âˆ†Go â€™rxn,303 = âˆ’ 4812 J/mol
(a) Write the form of the equilibrium constant for pyruvate +aspartate â†” alanine + oxaloacetate and calculate the numericalvalue of the equilibrium constant at 30o C.
(b) In the cytoplasm of a certain cell, the components are atthe following concentrations: pyruvate = 10-2 M, aspartate = 10-2M, alanine = 10-4 M, and oxaloacetate = 10-5 M. Calculate the Gibbsfree energy change for the reaction of part (a) under theseconditions. What conclusion can you reach about the direction ofthis reaction under cytoplasmic conditions?
