The energetics of the active ionic transport across biomembranes.
A model of the energetics concerning the active ionic transport across biomembranes is presented. According to this model, the transfer of energy is made between a donor molecule and a receiver molecule, this being the manifestation of some electronic transitions, with the release, transfer and storage of two quanta of electronic excitation. The transfer of energy is accompanied by an exchange of ions between the donor molecule and the receiver molecule. If the two coupled molecules are fixed in the structure of a biomembrane, this ionic shift produces an active ionic transport across the respective membrane. The energy necessary to the accomplishment of the active ionic transport results from the difference between the energy released by the donor molecule and the energy stored by the receiver molecule.
