Study Notes
Gibbs Free Energy and Bioenergetics
- Life on Earth maintains constant temperature and pressure (1 atm), enabling the study of bioenergetics through Gibbs free energy (ΔGo).
- Gibbs free energy (ΔGo) indicates the spontaneity of a reaction; a negative ΔGo signifies a favorable reaction.
- A reaction is spontaneous when the free energy of the products is lower than that of the reactants.
Favorable Reactions
- For a reaction represented by A + B ⇄ C + D, spontaneity is determined by the relationship between the Gibbs free energies of the compounds involved.
- The reaction is favorable when the combined free energy of products (GC + GD) is less than that of the reactants (GA + GB).
- This concept is essential in understanding biochemical processes and energy transfers in living organisms.
