Which part of the cell membrane is nonpolar? How does this property contribute to the function of the cell membrane?
Phospholipid's structure consists of a polar head and two non polar tails.
These tails do not allow polar molecules to pass in or out of the membrane. It does not allow soluble materials like glucose, proteins to leave the cell where as restrict unnecessary polar molecules to enter the cell. It plays an important role to make the membrane semi permeable.
