Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Fatty acid chains
The lipid bilayer prevents the cell from dissolving in water.
Nonpolar Fatty Acids
Phosphate groups
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Cell membrane have proteins embedded in them that act as channels for things to enter and leave the cell. Furthermore, the fact that the membrane is non-polar will block any polar molecules from entering but will allow non-polar molecules such as hormones to enter.
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
Fatty acid chains
Yes, polar molecules can pass through the cell membrane with the help of specific transport proteins.
The Cell membrane, along with its integrated proteins. In prokaryotes the Cell membrane is bolstered by the [mostly cellulosic] Cell Wall; in eukaryotes the Cell membrane is bolstered by the [glyco-protein] Cell Coat.
The lipid bilayer prevents the cell from dissolving in water.
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.
Nonpolar Fatty Acids
It's called membrane potential.
Because it is a small molecule, water can diffuse through the cell membrane.
