Abstract

The subject of the study was transportation of glucose molecules through a cuprophane membrane by the earlier devised method based on the phenomenon of light interference sensitive to changes in the optical density in two neighbouring chambers separated by a membrane. In the experiment the number of light and dark interference fringes and the rate of their movement through the observation slit were recorded. The analysis of time changes in the concentration of the solutions in the two chambers brings information on the dynamics and mechanism of glucose molecules transportation through the membrane.
