:
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,
