Ion Transport in Hydrodictyon africanum
The concentrations of K, Na, and Cl in the cytoplasm and vacuole, the tracer fluxes of these ions into and out of the cenocyte, and the electrical potential difference between bathing solution and vacuole and cytoplasm, have been measured in Hydrodictyon africanum. If the ions were acted on solely by passive electrochemical forces, a net efflux of K and Cl and a net influx of Na would be expect...
متن کاملLight Stimulation of Active Transport in Hydrodictyon africanum
The mechanism of light stimulation of active K and Cl influx and active Na efflux, in Hydrodictyon africanum has been investigated using different wavelengths of red light and different gas mixtures, and the inhibitors DCMU and CCCP. The active Cl influx requires photosystem 2, since its relative quantal efficiency falls with increasing wavelength of red light, and it is as sensitive to the inh...

متن کاملAn ultrastructural study of the relationship between the plasma membrane and the cell wall of the coenocytic alga hydrodictyon africanum.
A wall/plasma membrane unit was prepared from Hydrodictyon africanum by microdissection. A replica of the inner surface of the membrane was made and by freeze-fracture of the whole cell, 2 corresponding internal fracture faces were obtained. The large coenocytes of the alga were plasmolysed and the wall separated by cutting it away. Its inner surface was directly viewed in the electron microsco...
متن کاملCharacterization of Phosphate Membrane Transport in Saccharomyces cerevisiae CEN.PK113-5D under Low-Phosphate Conditions Using Aerobic Continuous Culture
Two different growth media, namely complex and defined media, were used to examine establishment of steady-state conditions in phosphate-limited culture system of Saccharomyces cerevisiae CEN.PK113-5D strain. Using the defined growth medium, it was possible to obtain steady state condition in the continuous culture. The effect of phosphate concentration on the growth of S. cerevisiae in pho...
