| Abstract: | Comparison of electric characteristics of photoreceptor disc and plasma membranes of photoreceptor was made by means of photopotential registration from the adhized to the impregnated by lipids filters photoreceptor discs or isolated rod outer segments. The resistance of the photoreceptor disc membrane is shown to be by three orders of magnitude higher than the resistance of photoreceptor plasma membrane; namely 1-2 MOhm X cm2 versus 1-2 KOhm X cm2. This is the evidence for the absence of channel structures in the disc membrane. |
