Cell membranes are composed of a lipid bilayer. It has different receptors that allow different ions to pass‚ depending on the conditions in the cell. Leak channels- always open allow ions to flow back and fourth across the cell membrane Na cl ‚K and Ca ions and they just flow back and fourth without any gate keeper or obstruction‚ When the neuron is at rest its cytoplasm is Negatively charged. That means that it is not going under depolarization‚ we use the term resting potential. Modality

Membrane Processing MEMBRANEFILTRATION A membrane or‚ more properly‚ a semipermeable membrane‚ is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Membrane filtration enables to separate particles with a diameter smaller than the pore diameter in the membrane from the liquid feed‚ by applying a driving force (pressure) over the membrane. The membrane technology consists principally of Microfiltration (MF)‚ Ultrafiltration
