Descriptor English:

Proton-Motive Force

Descriptor Spanish:

Fuerza Protón-Motriz

Spanish from Spain

Descriptor	fuerza motriz protónica
Entry term(s)	gradiente pH mecanismos quimiosmóticos pH delta
Scope note:	Energía generada por la transferencia de electrones o protones a través de una membrana transductora de energía y que puede utilizarse para realizar trabajo químico, osmótico o mecánico. La fuerza motriz protónica puede generarse por distintos fenómenos, como el funcionamiento de una cadena de transporte de electrones, la iluminación de una MEMBRANA PÚRPURA y la hidrólisis del ATP por una ATPasa protónica. (Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed, p171)

Scope note:

Energy that is generated by the transfer of protons or electrons across an energy-transducing membrane and that can be used for chemical, osmotic, or mechanical work. Proton-motive force can be generated by a variety of phenomena including the operation of an electron transport chain, illumination of a PURPLE MEMBRANE, and the hydrolysis of ATP by a proton ATPase. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed, p171)
