How does the aquaporin prevent h plus ions from passing through?

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.

Aquaporins are water channels that selectively allow the passage of water molecules while blocking the passage of ions, including H+ ions, due to their specific structure and size. The aquaporin's narrow pore does not allow ions to pass through easily, preventing them from moving across the membrane.

What is the electrolysis of copper sulfate?
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.
How do you make a penny the color gold?
One way to make a penny appear gold is to coat it with a layer of metallic gold through a process called electroplating. By using an electroplating solution containing gold ions and passing an electric current through it, the gold ions can be deposited on the penny's surface, giving it a gold appearance.
Describe how a cation exchange resin and a solution NaOH with a known concentration could be used to determine the amount of NaCl in an aqueous solution?
A cation exchange resin selectively exchanges Na+ ions for other cations in a solution. By passing the NaCl solution through the resin, all Na+ ions will bind to the resin and the Cl- ions will pass through. Subsequently, adding a known concentration of NaOH to the resin will displace the Na+ ions, allowing the amount of NaCl to be calculated based on the amount of NaOH needed to displace all the Na+ ions.
How can I Remove Ammonia from water?
Ammonia can be removed from water through processes like aeration, chlorination, or ion exchange. Aeration involves exposing water to air to allow the ammonia to volatilize and escape. Chlorination can help to convert ammonia into chloramines, which can then be removed through filtration. Ion exchange involves passing water through a resin that exchanges ammonia ions for other ions like sodium or hydrogen.
Why does current pass through salt solution but not through sugar solution?
In order to pass current through a solution you need to have ions in it. Table salt (NaCl) dissolves into Na+ and Cl- ions. Meanwhile sugar does not dissociate into ions in a water solution.
What prevents ions and most large molecules from passing through the membrane?
vacuoles
Where does the energy come from ATP at the chloroplast?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
Where does the energy come from to make at at the chloroplast?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
Where Does the energy comes from to make at the chloroplasts?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
Describe how the diffusion of ions across a cell membrane differs from the diffusion of nonpolar molecules across the cell membrane?
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.
Where does the energy come from to make ATP the chloroplast?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
What help to restore homeostasis in someone with water intoxication?
The reabsorption of salts and ions into the blood after passing through the kidneys.
Where does the energy come from to make ATP at the chloroplast?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
Do ions and other small water-soluble materials cross the cell membrane only by passing through the channels?
Im pretty sure this is a yes.
The interior of the lipid bilayer of a cell membrane forms a nonpolar zone that?
A nonpolar zone is formed in the interior portion of a cell membrane. This zone has the ability to prevent large molecules and ions from entering through the membrane.

What is electrolytic decomposition reaction?
a chemical decomposition reaction produced by passing an electric current through a solution containing ions is known as electrolytic decomposition reaction
