四、细胞各亚微结构间的关系: MITCHELL(1979)的化学渗透学说即己予见到线粒体内的PH较胞液的更偏碱性(图2C);pH梯度与线粒体膜电位是作为氧化还原能转变为ATP的磷酸化能的一种机理,正如细胞膜的情况一样,通过使“弱”离子(此处指H~+),与各种“强”离子交换的离子泵,(以维持pH的差异;这些离子中的一种是Ca~(++);其实,用离子透入法将CaCL_2注入蜗牛的神经原(图4C)引起与注入相同毫当量HCL一样的酸化,此现象源于被线粒体主动泵入并换 Fourth, the relationship between the cell sub-micro-structure: MITCHELL (1979) chemical permeation theory that has been seen within the mitochondrial pH more alkaline than cytosol (Figure 2C); pH gradient and mitochondrial membrane potential as oxidation A mechanism by which reductions can be converted to the phosphorylation energy of ATP, as is the case with cell membranes, is achieved by reacting “weak” ions (here H ~ +), ion pumps with various “strong” pH difference; one of these ions is Ca ~ (++); in fact, CaCl_2 injection into snail neurons by iontophoresis (Figure 4C) resulted in the same acidification as injecting the same meq HCL, In the mitochondrial active pump and change
