·        tails

·        fatty acids

·        two

·        The lipid bilayer consists of ___ rows of ___, with the ___ hydrophobic ___ forming the center of the bilayer. The ___ hydrophilic ___ are situated along the outside of the bilayer. This bilayer creates a separation between the contents of a cell and its surroundings.

Explanation / Answer

Hi, thank you for your question.

The lipid bilayer is composed of two layers of phospolipids. A phospholipid has a polar head which has phosphate group attached while the non-polar hydrocarbon part is called the tail. The tail is hydrophobic and repels water. The layer is structures so that non-polar tails are sandwitched between two layers of hydrophilic heads. So the complete statement with blanks filled is like:

The lipid bilayer consists of two rows of phospholipids, with the nonpolar hydrophobic tails forming the center of the bilayer. The polar hydrophilic heads are situated along the outside of the bilayer. This bilayer creates a separation between the contents of a cell and its surrounding.

Hope that helps. If you need further information, please do not hesitate to ask.
