Possible energy transmission along conjugating membranes was investigated. It was found by extracellular electrodes that under local illumination of blue-green algae Phormidium uncinatum the electrical current propagated along trichomes. The form and sign of the responses show that e. m. f. appears in the illumination region, which generates on the cellular membrane the potential difference with a negative charge inside the cell. The initiated transmembrane potential difference propagates along the filament of Ph, uncinatum like along a cable. The hypothesis concerning a cable structure of Ph, uncinatum was supported in the experiments with intersection of algae, and with intracellular injection of fluorescein showing the existence of direct diffusion exchange through cellular interfaces.
研究了沿共轭膜的可能能量传递。通过细胞外电极发现，在蓝绿藻束毛藻局部光照下，电流沿藻丝传播。响应的形式和符号表明，在光照区域出现电动势，该电动势在细胞膜上产生细胞内带负电荷的电位差。引发的跨膜电位差像沿电缆一样沿束毛藻的细丝传播。关于束毛藻电缆结构的假设在藻类交叉实验以及细胞内注射荧光素的实验中得到了支持，这些实验表明通过细胞界面存在直接扩散交换。
