AI Article Synopsis
- The model of electron transport incorporates the Mitchell Q-cycle to analyze fluxes of electrons and protons across the thylakoid membrane.
- The calculations for electron flux (Je) and proton flux (JH) depend on the light excitation of reaction centers and the acidity levels inside (pHin) and outside (pHout) the thylakoid.
- The stoichiometric ratio of proton to electron flux (JH/Je) is primarily influenced by the duration of plastoquinone reduction (tau B) and its restoration to the b/f complex (tau C) within photosystem II.
Article Abstract
On the basis of the earlier proposed model of electron transport, which takes into account the Mitchell Q-cycle, stationary values for the fluxes of electrons Je along the electron transport chain and of protons JH across the thylakoid membrane were obtained, which are calculated now as the functions of photoexcitation of reaction centers and the medium acidity inside and outside of the thylakoid, pHin and pHout. In the framework of the model, the stoichiometric ratio JH/Je is determined virtually only by the time of reduction of plastoquinone (tau B) on the B site of photosystem II and restoration of plastoquinone (tau C) on the C site to the b/f complex.
