Can polar molecules and molecules that have chargers sneak through the nonpolar middle portion of the phospholipid bilayer?
No, they are not. Micelles are formed by amphipathic molecules, that is molecules having both poplar and nonpolar regions, such as phospholipids or fatty acids. The polar region stays to the outside of the sphere as it can interact with water or some other polar solvent and the nonpolar regions are forced to the center.
What else can I help you with?
Can nonpolar molecules cross the lipid bilayer?
Yes, nonpolar molecules can cross the lipid bilayer because the lipid bilayer is made up of nonpolar molecules itself, allowing nonpolar molecules to pass through easily.
Can polar molecules pass through the phospholipid bilayer?
Yes, polar molecules can pass through the phospholipid bilayer through facilitated diffusion or active transport.
Do hydrophobic molecules cross cell membranes?
Yes, hydrophobic molecules can cross cell membranes because cell membranes are made up of a phospholipid bilayer that is permeable to nonpolar molecules like hydrophobic ones.
Two-layer sandwich of molecules that surrounds an organella or cell is called a?

What part of the cell membrane prevents the cell from dissolving in water?
Nonpolar Fatty acid chains
Can nonpolar molecules cross the lipid bilayer?
Yes, nonpolar molecules can cross the lipid bilayer because the lipid bilayer is made up of nonpolar molecules itself, allowing nonpolar molecules to pass through easily.
Can polar molecules pass through the phospholipid bilayer?
Yes, polar molecules can pass through the phospholipid bilayer through facilitated diffusion or active transport.
Is oxygen able to pass directly through the phospholipid bilayer?
Yes, oxygen molecules are small and nonpolar, allowing them to pass directly through the phospholipid bilayer of cells by simple diffusion. This is one of the reasons why oxygen can easily enter and exit cells to support cellular respiration.
Do hydrophobic molecules cross cell membranes?
Yes, hydrophobic molecules can cross cell membranes because cell membranes are made up of a phospholipid bilayer that is permeable to nonpolar molecules like hydrophobic ones.
A phospholipid molecule has a polar and a nonpolar end because of this water molecules form what kind of bond?
hydrogen bonds with the polar end of the phospholipid molecule
What does Phospholipid Bilayer?
The phospholipid bilayer is the outer layer of the cell. It only lets very small molecules through it. The bigger ones will have to go through the proteins lodged in the bilayer and the HUGE molecules will have to perform exocytosis or endocytosis
Is the polar head of a phospholipid made of molecules?
Phosphate molecules.
Why do integral proteins stay in place in the phospholipid bilayer?
Integral proteins are able to stay in the phospholipid bilayer because of the way they fold. Proteins have both hydrophic and hydrophilic regions that correspond to the regions of the phospholipid bilayer.
How do phospholipid molecules organize within a lipid bilayer?
Side-by-side

What kind of bi layer is the cell membrane?
The cell membrane is a phospholipid bilayer, consisting of two layers of phospholipid molecules. Each phospholipid molecule has a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails, creating a barrier that controls the movement of molecules in and out of the cell.
Why water molecules cannot diffuse directly through the phosolipids bilayer?
Water molecules are polar, while the interior of the lipid bilayer is nonpolar. This mismatch in polarity makes it energetically unfavorable for water molecules to pass through the hydrophobic interior of the lipid bilayer. Instead, water molecules move across cell membranes through specialized channels called aquaporins.
