Endergonic (from the prefix endo-, derived from the Greek word ἔνδον endon, `within`, and the Greek word ἔργον ergon, `work`) means `absorbing energy in the form of work.` Endergonic reactions are not spontaneous. By thermodynamic standards, positive work, a form of energy, is defined as moving from the surroundings (the external...
