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.
What is the definition of impermeable?
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
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.
What ions are positively charged and can cross back and forth across neuron and cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity
The side from which more water molecules cross the semipermeable membrane?
The pure solvent side is the side from which more water molecules cross the semipermeable membrane.
