In thermodynamics, endergonic, as contrasted with exergonic, refers to a free energy or available energy absorbing process or reaction, one in which work energy is consumed, defined by the criterion: ΔG > 0 (isothermal, isobaric process) or ΔF > 0 (isothermal, isochoric process).
In short, an endergonic reaction (or process) requires energy to proceed. [1]
