The extracellular ATP, Ca2+, Mg2+, ATP-Ca2+ and ATP + Mg2+ affect the optical density (at 520 nm) and turbidity spectra in suspensions of light and heavy synaptosomes and in mitochondria prepared from rat cerebral cortex. The properties of the light synaptosomes are associated only with their volume changes; the heavy synaptosomes and mitochondria also change their refractive indices. These results could be interpreted by structural (conformational) rearrangements occurring in membranes under such conditions. A support for this assumption was found in the studies on the spin-labeled synaptosomes.
细胞外的三磷酸腺苷（ATP）、钙离子（Ca2+）、镁离子（Mg2+）、ATP-Ca2+和ATP + Mg2+会影响轻、重突触体悬浮液以及从大鼠大脑皮层制备的线粒体在520纳米处的光密度和浊度光谱。轻突触体的特性仅与其体积变化有关；重突触体和线粒体的折射率也会发生变化。这些结果可以通过在这种条件下膜中发生的结构（构象）重排来解释。在对自旋标记突触体的研究中找到了对这一假设的支持。
