title: The Role of Ascorbate Free Radical as an Electron Acceptor to Cytochrome b-Mediated Trans-Plasma Membrane Electron Transport in Higher Plants.
abstract: The action of ascorbate free radical as an electron acceptor to cytochrome b-mediated trans-plasma membrane electron transport is demonstrated. Addition of ascorbate free radical to ascorbate-loaded plasma membrane vesicles caused a rapid oxidation of the cytochrome, followed by a slower re-reduction. The fully reduced dehydroascorbate was ineffective.
