Classified under:
Nouns denoting relations between people or things or ideas
Hypernyms ("concentration gradient" is a kind of...):
gradient (a graded change in the magnitude of some physical quantity or dimension)
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.

A research team led by Drs. Zoe F. Mann and Matthew W. Kelley at NIH’s National Institute on Deafness and Other Communication Disorders (NIDCD) suspected that a molecular concentration gradient may guide the cells during development.
