Is The hydrophobic part of a cell membrane is on the inside of the phospholipid bilayer?
hydrophobic
What is a cellmembrane?
A cell membrane is a phospholipid bilayer. It is made up of a hydrophilic head(the phosphorous part) and a hydrophobic tail(the lipid part). The hydrophobic tails face inward and the hydrophilic heads face the cytoplasm and the external solution.
What part of the cell membrane is polar and allows the cell to exits in water?
The cell membrane is made out of two layers , a nonpolar and polar part. The polar part is the hydrophilic part , meaning water loving , and the nonpolar is hydrophobic part - water hating. The polar/hydrophilic part is inside of the membrane and the outer portion is the hydrophobic/nonpolar . You don't want the cell to exist in water or be soluble in water because then we would dissolve , all our cells , tissues etc. That's why the cell membranes outer portion is nonpolar and is not miscible with water . The cell membrane allows water molecules to come in and out of the cell by osmosis , and that is when water molecules can free out and in of the cell through the cell membrane .
What part of the cell is the outer part of an animal cell?
The outermost structure of an animal cell is the cell membrane. The cell membrane is the membrane separating the interior of the cell from the outside environment. It is made up of proteins and lipids.
What part of the cell membrane prevents the cell from dissolving in water?
Nonpolar Fatty acid chains
Is The hydrophobic part of a cell membrane is on the inside of the phospholipid bilayer?
hydrophobic
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.
How are diffusion and facilitated diffusion diffrent?
Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the membrane.
Hydrophobic layer of the cell membrane?
The hydrophobic layer of the cell membrane consists of lipid molecules, such as phospholipids, arranged in a bilayer. This layer creates a barrier that prevents water-soluble molecules from freely passing through the membrane. Its hydrophobic nature helps maintain the structural integrity and selective permeability of the cell membrane.
What part of the cell is most important in maintaining homeostasis?
The cell membrane is the most important in maintaining homeostasis. This is because the cell membrane controls what goes in and out of the cell.
Which part of the lipids most likely the exterior portion of the cell membrane?
The hydrphilic head and the hydrophobic tail, absorb water. brought to you by j.

How do phospholipids contribute to membrane structure?
Since phospholipids have a hydrophobic tail (does not like water) and a hydrophillic head (likes water) it is best for a membrane structure. For the tail, it's usually bent at one end so phospholipids can attach to each other and usually never separate. Here's a visual representation: For a membrane, the phospholipids connect until they make a circle to sorround what is inside of the cell, but it is a bilayer membrane which means there will be 2 circles of phospholipids which looks like this (ignore the yellow part): Since the hydrophobic part is facing each other, it keeps the phydrophillic parts outside and inside of the cell (look at the link above). That means the water that usually sorrounds the cell cannot get into the cell because the hydrophobic part is in between the hydrophillic part. The one that does not like water will not allow the water to get into the cell.
What part of the cell is the outer part of an animal cell?
The outermost structure of an animal cell is the cell membrane. The cell membrane is the membrane separating the interior of the cell from the outside environment. It is made up of proteins and lipids.
What type of cell membrane cell is?
cell membrane is a part of the cell (organelle) not a cell
What is a cell Membrane and it's function?
In the animal cell, the cell membrane is the outer layer of the cell, that holds the organelles and the cytoplasm inside. It also allows things to get in and to get out of the cell. The cell membrane is also an important part of the plant cell too, but it is not the outer layer. It still has the same functions, but it is inside another part of the cell called the cell wall. The cell wall is the outermost part of a plant cell ind is stiffer and thicker than the cell membrane.
