endoergystically

Endoergystically is an adverb used to describe a process that requires a net input of energy to occur. The form is built from the prefix endo-, meaning within or internal, the root erg- from Greek ergon meaning work or energy, and the suffix -istically, forming an adverb. It is a neologism not widely adopted in formal scientific writing, and is often more common in speculative, pedagogical, or stylistic contexts. In many scientific disciplines, the concept is more commonly expressed with endergonic or endothermic terminology.

In chemistry and biochemistry, an endoergystically driven reaction or process would be one that is non-spontaneous under standard conditions and requires energy input, such as coupling with an energy-releasing step (e.g., ATP hydrolysis). The term can emphasize the manner in which energy is supplied, as opposed to merely the energy balance.

Usage note: Because endoergystically is not standard, readers should ensure clarity by defining the term when first used, and distinguishing it from endergonic (thermodynamics) or endothermic (heat absorption) where relevant.
