What would happen to a cell if the cell membrane was made of a molecule that did not repel water?
If the cell membrane was made of a molecule that did not repel water, the membrane would become permeable to water and other water-soluble molecules. This would disrupt the cell's ability to maintain internal conditions necessary for its normal functioning, potentially causing the cell to swell and burst due to osmotic imbalance.
Which molecule prevents cell membrane from dissolving in water?
Nonpolar Fatty Acids
Why do the lipids that make up the cell membrane arrange themselves into a bilayer?
because they have the ability to repel water (hydrophobic)
What molecule makes up the bulk of a cell's membrane?
Phospholipids make up the bulk of a cell's membrane. They have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which form a lipid bilayer that provides the structure and integrity of the cell membrane.
Which part of membrane is hydrophobic?
The lipid bilayer of the cell membrane is hydrophobic, composed of fatty acid tails that repel water molecules. This hydrophobic core provides a barrier that prevents water-soluble molecules from freely passing through the membrane.
What would happen to a cell if the cell membrane was made if a molecule that did not repel water?
it would not keep working to do its functions
What would happen to a cell if the cell membrane was made of a molecule that did not repel water?

How can water go through the cell membrane when it is polar?
Because it is a small molecule, water can diffuse through the cell membrane.
The fatty acids in the tail of a phospholipid molecule are what?
This is called the hydrophobic 'side' of the phospholipid molecule
Which molecule prevents cell membrane from dissolving in water?
Nonpolar Fatty Acids
What is the primary molecule of the cell membrane?
The primary molecule of the cell membrane is a phospholipid. Phospholipids have a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail, which allows them to form a double layer in the cell membrane called the phospholipid bilayer.
Why do the lipids that make up the cell membrane arrange themselves into a bilayer?
because they have the ability to repel water (hydrophobic)
What molecule does cell membrane contain?
The cell membrane contains phospholipids.
What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?
Carrier proteinsProteins in the cell membrane that assist with facilitated diffusion are known as carrier proteins since they carry materials across the membrane. Carrier proteins bind to a molecule on one side of the membrane, change shapes to shield the molecule from the lipid bilayer, and then release the molecule on the other side of the membrane
What Component of cell membrane that makes it impermeable to water?
The cell membrane is not impermeable to water but semi permeable which means it allowa only water to enter into the cell when the concentration of water molecules is higher in the fluid surrounding the cell than the fluid inside the cell.
Which term describes the movement of water molecule in and out of the cell?
The movement of water through a semipermeable membrane is called osmosis.
What terms describes the movement of water molecule in and out of cell?
The movement of water through a semipermeable membrane is called osmosis.
