Free energy change of hydrolysis
WebQuestion: Given that the standard free energy change of ATP hydrolysis is –30.5 kJ/mol, what is the change in free energy in a cell at 37 °C where the ATP and Pi are both 10 … WebThe of the thiohemiacetal produces an acyl thioester intermediate, which has a large free energy of hydrolysis. However, the free energy required to form the bond in 1,3-bisphosphoglycerate is the free energy change from thioester hydrolysis. The reverse reaction therefore results in a net negative free energy change.
