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.
What counteracts the movement of bicarbonate ions from the RBC?
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.
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.
What prevents ions and most large molecules from passing through the membrane?
vacuoles
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
Where does the energy come from ATP at the chloroplast?

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
Describe how the diffusion of ions across a cell membrane differs from the diffusion of nonpolar molecules across the cell membrane?
Ions undergo facilitated diffusion through ion channels or active transport mechanisms due to their charge, whereas nonpolar molecules diffuse freely through the cell membrane by simple diffusion. Ion movement is regulated and specific, while nonpolar molecules move passively without the need for specific channels or transporters.
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?
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.

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
What is iron exchange method to clean water?
Iron exchange is a water treatment process that involves removing iron from water by passing it through a special resin that exchanges iron ions for sodium ions. As the water flows through the resin bed, the iron ions are captured by the resin and replaced with sodium ions, effectively removing the iron from the water. This method is commonly used to treat water with high iron concentrations, improving its taste and clarity.
