A lot of selectivity in any protein is often do to charges of particular amino acid residues. Aquaporin will let through H2O which has a 0 charge, but H+ ions are charged and won't pass through them.
The electrolysis of copper sulfate involves passing an electric current through a solution of copper sulfate, which contains copper (II) ions and sulfate ions. At the anode, copper (II) ions are discharged as copper metal, which coats the cathode. This process allows for the purification and electroplating of copper.
One effective way to remove hardness from water is through a process called ion exchange. This involves passing the water through a resin that exchanges calcium and magnesium ions, which cause hardness, for sodium ions. This results in softened water that is free from hardness minerals.
Deionized water is made by removing ions and impurities from regular water through a process called deionization. This involves passing the water through special filters or resins that attract and trap the ions, leaving behind pure water with a very low conductivity.
Electrolysis is used in the extraction of zinc from its ore by passing an electric current through a solution containing zinc ions. This process causes the zinc ions to gain electrons and form solid zinc metal, which can then be collected.
Chloride ions can counteract the movement of bicarbonate ions from red blood cells through a process known as the chloride shift. In this process, chloride ions move into the red blood cells as bicarbonate ions move out, helping to maintain electrochemical equilibrium and prevent excessive accumulation of bicarbonate in the plasma.

Ions need to be facilitated through a cell membrane because they are passing through a phospholipid bilayer with a hydrophobic interior. Non polar molecules are also hydrophobic, so they can pass through the membrane easily if they are small enough. Ions are polar, so they have a hard time passing through membranes.

No, ions and other small water-soluble materials can also cross the cell membrane through processes like simple diffusion or facilitated diffusion, in addition to passing through specific channels. Additionally, active transport mechanisms can move ions against their concentration gradient, requiring energy input.

Tight junctions are specialized cell junctions that prevent substances from passing between adjacent cells. They create a barrier by sealing the space between cells, ensuring that materials must pass through the cells themselves rather than between them. This is crucial for maintaining the integrity of epithelial tissues and controlling the movement of ions and molecules across cell layers.
