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 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.
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.
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.
Cleo's H20 locket is typically depicted as blue or aquamarine in color.
H2O is water, HF is hydrogen fluoride, and NH3 is ammonia.
Water.
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.
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
Yes, pyruvate can cross the mitochondrial membrane through specific transport proteins.
Yes, small hydrophobic molecules can cross the cell membrane.
Yes, nonpolar molecules can cross the cell membrane through simple diffusion.

A selectively permeable membrane allows SOME but not ALL materials to cross.
It is the ability of the membrane to allow ions and/or particles to cross.
