Light 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 کاملIon 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 کاملgradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism
ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
15 صفحه اولAn 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...
