What is the free energy of hydrolysis?
Biochemical free energies are usually given as standard free energies of hydrolysis. For example, the hydrolysis of glucose?6?phosphate: has ?G° = ?4.0 kcal/mole (?16.5 kJ/mole) under standard conditions.How do you calculate free energy of hydrolysis?
We can calculate the actual Gibbs free energy change for ATP hydrolysis (to ADP) given the known concentrations of reactants and products in rat hepatocytes. The answer is ?G = -48 kJ mol-1. Thus, the actual Gibbs free energy change is 1½ times the standard Gibbs free energy change.How many kJ of free energy in ATP hydrolysis?
Under “standard” conditions (i.e. concentrations of 1M for all reactants except water which is taken at its characteristic concentration of 55M) the Gibbs free energy of ATP hydrolysis varies from -28 to -34 kJ/mol (i.e. ?12 kBT, BNID 101989) depending on the concentration of the cation Mg2+.- Hydrolysis of ATP provides 7.3 kcal of energy, more than enough to power this reaction. Movement of four sodium ions across the membrane, however, would require 8.4 kcal of energy, more than one ATP molecule can provide.
