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.
本文提出了一个关于生物膜上主动离子转运的能量学模型。根据该模型,能量在供体分子和受体分子之间传递,这是一些电子跃迁的表现,伴随着两个电子激发量子的释放、转移和存储。能量转移伴随着供体分子和受体分子之间的离子交换。如果这两个耦合分子固定在生物膜结构中,这种离子移动会导致跨相应膜的主动离子转运。完成主动离子转运所需的能量来自供体分子释放的能量与受体分子存储的能量之间的差值。
