Phosphokinase reaction
WebIn the reaction, the CK catalyzes the transfer of a phosphate group from the creatine phosphate substrate to adenosine diphosphate (ADP). The subsequent formation of adenosine triphosphate (ATP) is measured through the use of two coupled reactions catalyzed by hexokinase (HK) and glucose-phosphate dehydrogenase -6 WebThe standard state free energy for hydrolysis of creatine phosphate is -43.1 kJ/mol and for the hydrolysis of ATP is -30.5 kJ/mol. Calculate the standard-state free energy change and equilibrium constant for the creatine phosphokinase reaction at …
