MODULE 1 EXAM: FOUNDATIONS OF BIOCHEMISTRY
Question 1
True or False: According to the Module, a compound with a molecular mass of
1,000 g/mol is considered a macromolecule.
A) True
B) False
Correct Answer: B
Rationale: The module defines a macromolecule as having a molecular mass
greater than 5,000 g/mol. A compound with a molecular mass of 1,000 g/mol is
too small to be classified as a macromolecule .
Question 2
True or False: Biomolecules can have only two functional groups.
A) True
B) False
Correct Answer: B
Rationale: Biomolecules can have multiple functional groups. For example, amino
acids contain both amino and carboxyl groups, and carbohydrates contain multiple
alcohol groups. The statement that biomolecules can have only two functional
groups is incorrect .
,Question 3
Of the following, which is NOT a property of carbon?
A) Forming cyclic structures
B) Forming multiple bonds
C) Forming bonds with oxygen
D) Forming ionic bonds
E) Bonding in long chains
Correct Answer: D
Rationale: Carbon forms covalent bonds, not ionic bonds. Carbon is able to form
strong covalent bonds, long chains, double/triple bonds, and cyclic structures. It
does not typically form ionic bonds because it has four valence electrons and
shares them rather than transferring them .
Question 4
What element has been called the "superglue" of the chemical world?
A) Nitrogen
B) Oxygen
C) Hydrogen
D) Carbon
Correct Answer: D
Rationale: Carbon is called the "superglue" of the chemical world because it can
form stable covalent bonds with many different elements, including itself. Carbon
is the basis for life and forms the backbone of all organic molecules .
Question 5
Scientists refer to ______ as the "super glue" of the chemistry world.
, A) C
B) Co
C) Na
D) C
E) O
Correct Answer: C
Rationale: Carbon (C) is known as the "super glue" of the chemical world due to its
ability to form strong covalent bonds with a variety of elements. This property
allows carbon to serve as the backbone for organic molecules and the basis for
life .
Question 6
What energy molecule is produced via respiration?
A) DNA
B) RNA
C) ATP
D) Creatine
Correct Answer: C
Rationale: ATP (adenosine triphosphate) is the primary energy molecule produced
via cellular respiration. It stores and transfers energy within cells for various
metabolic processes .
Question 7
According to the module, the study of NON-carbon compounds is referred to as:
A) Organic chemistry
B) Biochemistry
C) Inorganic chemistry
D) Environmental chemistry
