What role do aquaporins play in osmosis?
Aquaporins are specialized proteins that facilitate the movement of water molecules across cell membranes. In the context of osmosis, aquaporins help maintain the balance of water inside and outside of the cell by allowing water to move in and out of the cell freely, promoting osmotic equilibrium. This process is essential for maintaining proper cell hydration and homeostasis.
Does transporting aquaporins proteins require ATP?
No, transporting aquaporin proteins does not require ATP. Aquaporins facilitate the movement of water across cell membranes through passive transport processes, such as osmosis or simple diffusion according to the concentration gradient. ATP is typically not needed for passive transport.
How did Agre use simple osmosis experiment to prove the function of aquaporin?
Agre tested his hypothesis in a simple experiment where he compared cells which contained the protein in question with cells which did not have it. When the cells were placed in a water solution, those that had the protein in their membranes absorbed water by osmosis and swelled up while those that lacked the protein were not affected at all. Agre also ran trials with artificial cells, termed liposomes, which are a type of soap bubble surrounded on the outside and the inside by water. He found that the liposomes became permeable to water if the protein was planted in their membranes.
Does osmosis require membrane proteins?
No, osmosis is a special type of diffusion in which a water molecule is able to passively transport through a membrane without a protein. Although it is polar, it's extremely small size makes this possible
What does osmosis move?
Osmosis moves water molecules across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration, in order to equalize the solute concentration on both sides of the membrane.
What is helped by aquaporins?
osmosis
Are aquaporins involved in osmosis or facilitated diffusion?
Aquaporins are involved in osmosis by facilitating the movement of water molecules across cell membranes. They do not participate in facilitated diffusion, which involves the transport of solutes across membranes with the help of carrier proteins.

In the context of osmosis, aquaporins help maintain the balance of water inside and outside of the cell by allowing water to move in and out of the cell freely, promoting osmotic equilibrium.

How does water reabsorption in kidneys occur?
by osmosis through tubular aquaporins
The diffusion of water across a selectively permeable membrane through aquaporins is called?
osmosis
What protein aids in osmosis I didn't hear all of what my teacher said but I heard that the first part was aqua?
You might be looking for Aquaporins. Realize that that is not the only type of protein that can aid in osmosis. Aquaporins are a type of Channel Protein. There there are Carrier Proteins that serve a similar purpose, but do it differently. You can look this up in your class literature for verification.
What channel proteins allow water to pass across the membrane?
Aquaporins

What channel is used in osmosis?
In osmosis, water molecules move across a semi-permeable membrane from an area of high concentration to an area of low concentration. This movement occurs through special channels called aquaporins, which allow water molecules to pass through the membrane.
