The Change in Gibbs Free Energy for a Particular Reaction

Question

The change in Gibbs free energy for a particular reaction is most useful in determining
A) the amount of energy catalysts required for biosynthesis or catabolism.
B) the potential metabolic reaction rate.
C) whether there will be a requirement or production of energy.
D) energy stored in each compound.

Accepted Answer

The change in Gibbs free energy (ΔG) measures whether a reaction is exergonic (produces energy) or endergonic (requires energy) and can therefore determine whether there will be a requirement or production of energy. It does not provide information on the amount of energy catalysts required or the potential metabolic reaction rate, and only indirectly relates to the energy stored in each compound.
