Question 1
Many single-celled organisms rely primarily on
monosaccharides and disaccharides as their source
of energy. Which class of biomolecules provides
the energy for these cells?
Answer
Monosaccharides and disaccharides are simple
sugars which makes them carbohydrates.

Question 2
Fats provide long term energy storage and
insulation to the human body. Fat molecules are
a member of which class of biomolecules?
Answer
Fat molecules are a form of lipid.

Question 3
What class of biomolecule is shown to the right?
Answer
Amino acids are the building blocks of proteins.
5
Question 4
Which class of biomolecule carries the cells
instructions in the form of genetic material?
Answer
Nucleic acids (DNA and RNA) are the genetic
material of the cell.

Question 5
The diagram shown depicts which class of
biomolecule?
Answer
Sugars are the monomers which make up complex
carbohydrates.
7
Question 6
Which class of biomolecule is NOT primarily
composed of polymers?
Answer
Lipids are NOT considered polymers.
8
Question 7
Short chains belonging to which class of
biomolecules are often referred to as polypeptide
chains?
Answer
Polypeptides are short chains of amino acids.
This makes them proteins!

Question 9
The diagram to the right best represents which
class of biomolecules?
Answer
Fats are made of glycerol and fatty acids, and
fats are a form a lipid.

Question 10
What class of biomolecule contains nitrogen bases?
Answer
Nucleic acids contain nitrogen bases in each
nucleotide.

Question 11
You need a steady supply of amino acids in your
diet to maintain a healthy body. In order to
meet this need, you should make sure you eat
enough of which class of biomolecule?
Answer
Your body digests proteins to get new amino acids
for making its own proteins.

Question 12
Which class of biomolecule is used to make cell
membranes?
Answer
Lipids, specifically phospholipids, are used to
make membranes.

Question 13
ATP is a member of which class of biomolecule?
Answer
ATP is a modified nucleotide which are the
monomers of nucleic acids.

Question 15
What is one of the two biomolecules that are
primarily used as energy sources by cells?
Answer
Carbohydrates and lipids are the primary sources
of energy for most cells.
