What structure regulates the movement of water into and out f a cell?
Cell membrane, specifically aquaporin proteins, regulate the movement of water into and out of the cell through a process called osmosis. These proteins create channels that selectively allow water molecules to pass through, maintaining proper water balance in the cell.
What are the special structures in the cell membrane that allow materials such as water and sugar to pass through made o?
The special structures in the cell membrane that allow materials like water and sugar to pass through are proteins called transport proteins. These proteins help facilitate the movement of specific molecules across the membrane by acting as channels or carriers. They play a crucial role in regulating the flow of substances in and out of the cell.
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes.
How do molecules get in and out of cell?
polar molecules are repelled by the cells electrical charge.
Do some membranes have proteins with chanels that allow for the passage of hydrophilic substances?
Yes, some membranes have protein channels called aquaporins that allow for the passage of hydrophilic substances like water across the membrane. These channels facilitate the movement of water molecules while excluding other substances.

Are aquaporins transport proteins responsible for facilitating the movement of water across cell membranes?
Yes, aquaporins are transport proteins that facilitate the movement of water across cell membranes.

Yes, some membranes have protein channels called aquaporins that allow for the passage of hydrophilic substances like water across the membrane. These channels facilitate the movement of water molecules while excluding other substances.
What name is given to the trans-membrane proteins that allow the direct passage?
The name given to the trans-membrane proteins that allow the direct passage of small molecules across the cell membrane is "channel proteins." They form channels or pores that facilitate the movement of specific ions or molecules across the membrane.
What structure allows sugar and water to pass through?
Cell membrane allows sugar and water to pass through due to the presence of transport proteins such as glucose transporters and aquaporins. These proteins facilitate the movement of these molecules across the cell membrane through passive or active transport processes.
What are the membranes of what have tiny pores that allow the passage of water molecules?
Cell membranes have tiny pores that allow the passage of water molecules. These pores are formed by specialized proteins called aquaporins, which facilitate the movement of water across the membrane. Aquaporins help maintain water balance within cells and regulate water transport in and out of the cell.
Is osmosis a movement of proteins?
No, in osmosis water molecules move from higher water concentration to a lower concentration through a semi-permeable membrane. Proteins are much smaller matter.
What channel proteins allow water to pass across the membrane?
Aquaporins
