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.

What is difference between hydrolysis and electrolysis?
Hydrolysis is the chemical breakdown of a compound due to reaction with water and electrolysis is the chemical decomposition produced by passing an electric current through a liquid or solution containing ions.
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.
Explain A charge insulator can be discharge by passing it just above a flame?
A charged insulator can be discharged by passing it just above a flame because a flame has a cloud of ions above it. Even though the overall charge above the flame is neutral, a charged insulator will use up the ions that it needs and neutralize.
Is NaCL formed through ionic bonding?
*The formula is NaCl. It is formed through ionic bonding due to the strong electrostatic attractions between the positive sodium ions (Na+) and the negative chloride ions (Cl-).
What happens to the concentration of sulphuric acid as the electricity is passed through it?
the h2 ions and the so4 ions in the sulphuric acid help electricity pass through it. this makes it a strong electrolyte.(electrolyte- a liquid which conducts electricity)
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
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.
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.
Why do you think movement of ions through ion channels is generally a slower process that diffusion?
Let's take something obvious. Where would a crowd of persons move faster? Where there is absolutely nothing to prevent their passage or where there is an open gate? The same thing applies to the movement of ions. Movement of ions through ion channels is a slower process because (with a more scientific approach!) their movement is determined by the number of these ion channels whereas for diffusion, there is absolutely nothing to prevent the passage of the molecules.
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
