Phospholipids are an essential component of the phospholipid bilayer necessary to the cell.
Which of the following correctly represents a phospholipid subunit with the corresponding polarity?
A phospholipid generally consists of a phosphate head (polar) and a fatty acid tail (non-polar).
Compare your answer with the correct one above
The phospholipid bilayer is critically important to the separation of the internal and external environment of the cell.
What drives the formation of the phospholipid bilayer?
The external hydrophilic environment attracts polar hydrophilic phosphate head groups to the exterior, while allowing non-polar hydrophobic fatty acids to remain shielded in the interior of what becomes the phospholipid bilayer.

Lipids are made up of hydrocarbons linked to each other.
A hydrocarbon involves an atom of carbon with how many hydrogen atoms bonded to it?
A hydrocarbon is made up of a carbon and two hydrogen atoms attached to it.

Which organic compound serves as stored energy for living things?
Lipids make up the bulk of fat in animal tissues and thus stores energy.

Plants often have a waxy covering on the outside of their leaves to prevent water loss. This waxy covering probably contains mostly which organic compound?
Major lipid groups include fats, steroids, and waxes. Because the question references a "waxy covering," we know that the plant covering must be composed of lipids.

Which of the following macromolecules are composed of long chains of amino acids?
By process of elimination, lipids and fats cannot be the correct answer-they are synonymous (lipids are also known as fats). Carbohydrates, eg sugars and starches are composed only of carbon, hydrogen, and oxygen. Nucleic acids contribute to DNA and RNA structure and function. The correct answer is proteins, made of long chains of amino acids-amino acids are sometimes called the "building blocks" of proteins.
