The Ferricyanide-Driven Redox System at the Plasmalemma of Plant Cells: Origin of the Proton Production and Reappraisal of the Stoichiometry e−/H+
Chapter
Abstract
An external acidification has been found associated with the activity of the ferricyanide-driven redox system at the plasmalemma of animal and plant cells [see 1, 2, 3 for reviews]. This has been interpreted as evidence that the transfer of electrons across the plasmalemma is accompanied by a release of protons from the cells [4, 5]. This conclusion has been formalized by assuming that the redox system at the plasmalemma of plant cells functions as a redox H+ pump [6, 7].
