In this paper, a model of the chemical energy conversion into mechanical energy is presented. According to this model, for each stage, the transfer of the energy is produced in the framework of a polymolecular system composed by a donor molecule, an enzyme and an acceptor molecular couple. The energy is released in the form of two quanta of electronic excitation. The transfer of the energy determines the change of the orbital directions, as well as the ionic constellations previously fixed at the level of the donor molecule and at the level of the acceptor molecular couple. Subsequently, an allosteric modification of the enzyme which connects the donor with the acceptor molecular couple is produced. The conversion of the chemical energy into mechanical energy is explained by means of the ions movement and by the conformational changes of the enzymes involved in the processes of the energy transfer.
本文提出了一种化学能转化为机械能的模型。根据该模型，在每个阶段，能量转移是在由供体分子、酶和受体分子对组成的多分子系统框架内产生的。能量以两个电子激发量子的形式释放。能量转移决定了轨道方向的变化，以及先前固定在供体分子水平和受体分子对水平的离子构型。随后，连接供体与受体分子对的酶发生别构修饰。化学能向机械能的转化通过离子运动以及能量转移过程中所涉及酶的构象变化来解释。
