 Context examples: 

Ion Exchanger Interaction consists of temporary non-covalent binding of a molecule through intermolecular physical forces of attraction with a membrane associated enzyme, or complex, involved in ATP-dependent transmembrane transport of a positively (cation) or negatively (anion) charged atom or radical against a concentration gradient resulting directly from the expenditure of energy.

(Ion Pump Interaction, NCI Thesaurus)

Anion Transporter Binding involves temporary non-covalent interaction of a molecule through intermolecular physical forces of attraction with an anion transporter protein that moves the bound ion carrying a negative charge across a cell membrane with or against a concentration gradient.

(Anion Transporter Binding, NCI Thesaurus)

ABC Transporter Binding involves temporary non-covalent interaction of a molecule through intermolecular physical forces of attraction with the ABC Transporter complex to move the substrate across the plasma cell membrane against a concentration gradient.

(ABC Transporter Binding, NCI Thesaurus)

The chemical energy that started with glucose, and was transferred to NADH and FADH2, is then converted to the energy of a concentration gradient.
