What is the standard free energy change in a biochemical reaction?
For biochemical reactions, the standard free-energy change is usually expressed as ?G°?, which is the standard free-energy change of a reaction in aqueous solution at pH= 7, approximately the conditions within a cell.What is the standard biochemical free energy change of 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+.What is the concept of free energy and standard free energy change in bioenergetics?
Free energy in bioenergetics is the amount of energy that is capable of doing work; the amount of available energy. It has a simple calculation. The change in free energy = change in enthalpy - (temperature times change in entropy). Temperature unit is Kelvin in this equation.- The ?G°' term is called the change in Standard Gibbs Free energy, which is the change in energy that occurs when all of the products and reactants are at standard conditions and the pH is 7.0. It is a constant for a given reaction. For most biological systems, the temperature, T, is a constant for a given reaction.
