standard free energy change is additive here free energy change of ATP hydrolysis is used in the synthesis of creatine phosphate so only 30.5kJ.mol is released upon ATP hydrolysis and for the formation of creatine phosphate requires 40.3 kJ/mol so it requires 40.3kJ/mol-30.5kj/mol=12.6 kJ/mol so this reaction requires extra 12.6 kJ/mol so answer is b)12.6 kJ/mol

For the following reaction: ATP+ creatine + H2O creatine phosphate + ADP + P, The relevant half reactions are: ATP → ADP + Pi Creatine phosphate + H2O-> creatine AG-30.5 kJ/mol ΔG°,--43.1 kJ/mol a. (2 pts.) Calculate the ΔG°, for the overall reaction. b. (2 pts.) Is the reaction spontaneous or non-spontaneous? Endergonic or exergonic?
To answer this question, please reference the Problem Solving Video: Free Energy, ATP, and Creatine in Resting Muscles. The standard free energy, AGⓇ', value for an enzymatic reaction with several al components is the sum of the AGⓇ values for each component. Creatine kinase catalyzes the transfer of a phosphate group from creatine phosphate to ADP to form ATP.
