Aquaporin Water Channels. A special protein channel with a polar side lets water in but not other substance. The water must aline itself and slide through the narrow channel. Also known as osmosis. For more info look up "Aquaporin Water Channels" Nobel Prize in Chemistry Winners.
Water (H2O) can cross the cell membrane through a process called osmosis, which is the movement of water molecules from an area of high concentration to an area of low concentration. Water can also pass through specialized protein channels called aquaporins that are embedded in the cell membrane to facilitate its movement.

Which type of molecules cross the membrane in osmosis?
Water molecules cross the membrane during osmosis. Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
How can oxygen cross through the membrane?
Oxygen can cross through the membrane via simple diffusion, utilizing a concentration gradient from an area of higher concentration to an area of lower concentration. This passive transport process does not require energy and allows oxygen molecules to move freely across the cell membrane.
Where is h20 produced in aerobic respiration?
In aerobic respiration, H2O is produced during the electron transport chain as a byproduct of the reaction between oxygen and hydrogen ions (H+) to form water. This final step of the electron transport chain occurs in the inner mitochondrial membrane.
What color is cleo's h20 locket?
Cleo's H20 locket is typically depicted as blue or aquamarine in color.
What substances will cross the cell membrane through osmosis?
Water is the primary substance that crosses the cell membrane through osmosis. Other small, uncharged molecules like oxygen and carbon dioxide can also pass through the cell membrane via osmosis.
What has high concentration in cell membrane?
Water.
Which substances are able to cross the membrane, and what determines their ability to do so?
Certain substances, such as small molecules and ions, are able to cross the cell membrane. The ability of a substance to cross the membrane is determined by its size, charge, and solubility in the lipid bilayer of the membrane.
What is the definition of impermeable?
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
Can pyruvate cross the mitochondrial membrane?
Yes, pyruvate can cross the mitochondrial membrane through specific transport proteins.
Can small hydrophobic molecules cross the cell membrane?
Yes, small hydrophobic molecules can cross the cell membrane.
Can nonpolar molecules cross the cell membrane?
Yes, nonpolar molecules can cross the cell membrane through simple diffusion.
Which feature of a membrane describes molecules whether can cross the membrane?
permeability
Which molecule of a membrane describes whether molecules can cross the membrane?
permeability
What feature of membrane describes whether molecules can cross the membrane?
permeabiity
What feature of a membrane describes whether molecule can cross the membrane?
permeabiity
What type of membrane allows some but not all materials cross?
A selectively permeable membrane allows SOME but not ALL materials to cross.
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
