Calculate the reaction enthalpy, entropy, and free energy, Hr0,Sr0,Gr0, for the amindation of glutamate to glutamine (1) at standard temperature, (2) at 37 deg C,
Calculate the reaction enthalpy, entropy, and free energy, Hr0,Sr0,Gr0, for the amindation of glutamate to glutamine (1) at standard temperature, (2) at 37 deg C, (3) at 75 deg C (a) taking into account the temperature dependence of H,S, and (b) assuming that H and S are temperature-independent. What can you conclude about the importance of C ? What does the result mean for organisms that live at moderate temperature (37 deg C; mesophilic organisms) and thermophilic organisms that live at 75 deg C ? Glutamine: Hf0=826kJ/mol,Cp,m=184J/molK,Sm=195J/molK Glutamate: Hf0=1010kJ/mol,Cp,m=175J/molK,Sm=188J/molK H2O:Hf0=290kJ/mol,Cp,m=75J/molK,Sm=70J/molK NH4:Hf0=133kJ/mol,Cp,m=80J/molK,Sm=113J/molK
