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.
