Angiogenesis

Molecular Aspects of the Neurotransmission by the Acetylcholine Receptor System, a pathway (channel) for the flow of Na. and K. ions is opened that causes depolarisation of the postsynaptic membrane. Rapid depolarisation, in turn, triggers the action potentials that are necessary for the muscle cell contraction or the discharge of the electric organ electrocytes.

PRO

Protein Translocation Across Biological Membranes,proteins have their functional location in subcellular compartments that are separated from the cytosol by at least one membrane. Certain proteins, for example, those residing in the lumen of chloroplast thylakoids, have to be translocated across as many as three bilayers to reach their destination.

Electrical Currents Induced by Ion Pumps on Black Lipid Membranes,brane fragments containing the ion-pump to a planar lipid film. As examples the light-driven pump Bacteriorhodopsin and the Na.K.-ATPase from pig kidney have been investigated. In a short circuit experiment the displacement and pump currents were detected . the capacitive coupling between the membra

In addition, the selective active transport of ions and the resulting ion concentration differences lead to the formation of transmembrane potential differences (shortly called .). Both surface potentials and membrane potentials

Insufficient

Factors Controlling the Ion Conductance of Channels,een ions and the highly polarizable fluid, water, means that a great deal of energy is needed to remove ions from water. The low polarizability of the lipid environment in the membrane does not interact strongly with ions and therefore acts as a good barrier to ion flux. For these reasons, ion flux
