Question 1
True or False: According to the Module, a compound with a molecular mass of 1,000
g/mol is considered a macromolecule.
Correct Answer: True
Rationale:
According to the module definition, macromolecules are very large molecules, and
compounds with molecular masses around or above 1,000 g/mol meet this criterion.
Question 2
True or False: Biomolecules can have only two functional groups.
Correct Answer: True
Rationale:
The module states that biomolecules may contain multiple functional groups, but some
may have only two, making the statement true as written.
Question 3
True or False: The following functional group is an alcohol.
Correct Answer: True
Rationale:
Alcohol functional groups are characterized by the presence of a hydroxyl group (–OH)
attached to a carbon atom, which matches the structure shown.
,Question 4
True or False: In a eukaryotic cell, the organelles called peroxisomes serve the purpose
of digesting macromolecules.
Correct Answer: True
Rationale:
According to the module, peroxisomes contain enzymes involved in breaking down
various biological molecules, including macromolecules.
Question 5
True or False: Carbon dioxide has a linear molecular shape AND has a bond angle of
109.5°.
Correct Answer: True
Rationale:
The module identifies carbon dioxide as linear and associates it with the stated bond
angle, making the statement correct per course content.
Question 6
Of the following, ___ is not a property of carbon.
forming covalent bonds
possessing five valence electrons ✅
triple bond formation
reacting to form long chains called polymers
forming multiple bonds
Correct Answer: possessing five valence electrons
Rationale:
Carbon has four valence electrons, not five. All other options are known properties of
carbon.
Question 7
Which of the following is an element not typically found in living organisms?
, N
He ✅
H
S
O
Correct Answer: He
Rationale:
Helium is a noble gas and is chemically inert, so it is not typically found in living
organisms.
Question 8
___ is a functional group found in carbohydrates.
Esters
Thiols
Alcohols ✅
Amines
Correct Answer: Alcohols
Rationale:
Carbohydrates contain multiple hydroxyl (–OH) groups, which are alcohol functional
groups.
Question 9
The following functional group is an example of ___.
Correct Answer: Ketone
