Membran Fonksiyonlarına Katyonların Etkisi

Abstract

The Effects of Cations on the Function of Cell Membrane |/ It is well known that zinc has a role in the membrane stabilization. The effects of zinc and other cation in respond to temperature stimulation on membrane stabilization of yeast cell were investigated. Several solutions were made for the yeast cells. 8-10 drips 0.5% congo red was added into solution which can not pass through the intact membrane. At the end of incubation, the rate of cell, in the experiment and control groups was obtained by counting the number of cells which was stained with congo red under the light micros¬cope (x400). The data show that divalent cation protect the cell membrane against to tem¬perature stimuli, while monovalent cation has no effect. It was assumed that divalent ca¬tions show their protective effects by binding membrane proteins and lipoproteins.
