An endergonic reaction (such as photosynthesis) is a reaction that requires energy to be driven. The activation energy for the reaction is typically larger than the overall energy of the exergonic reaction(1). Endergonic reactions are nonspontaneous. The progress of the reaction is shown by the line. The change of Gibbs free energy (Î´G) during an endergonic reaction is a positive value because energy is gained (2).
