Calculate the actual, physiological AG for the reaction
Phosphocreatine
Creatine
NH--PO3
HN=c
NCH,-CO0
NH2
NH=c.
HNCH2- COO
ČH3
Creatine
ADP
phosphokinase
АТР
At 37 °C, as it occurs in the cytosol of neurons, with phosphocreatine at 4.7
mM, creatine at 1.0 mM, ADP at 0.73 mM and ATP at 2.6 mM.
HINT:
AG° = 30.5 kJ/mol
AG° = -43.0 kJ/mol
ADP + Pi -> ATP + H,0
Phosphocreatine + H2O -> creatine + Pi
