PROGRAM: Chemistry / Biochemistry Program
COURSE NUMBER: CHEM 210
COURSE NAME: Biochemistry
EXAM NAME: Module 1, 2, 3, 4, 5, 6, 7 & 8 Exam (Biochemistry)
CHEM 210: MODULE 1-8
,Question 1
True or False: According to the Module, a compound with a molecular mass of
3,000 g/mol is considered a macromolecule.
Answer: False
Rationale: Macromolecules generally have molecular masses much larger than
3,000 g/mol, often tens of thousands to millions of g/mol.
Question 2
True or False: Biomolecules can have only two functional groups.
Answer: False
Rationale: Biomolecules may contain multiple functional groups, such as
hydroxyl, carboxyl, amino, phosphate, and carbonyl groups.
Question 3
True or False: The following functional group is an amide.
Answer: False
Rationale: The structure shown is not an amide. An amide contains a carbonyl
group (C=O) directly bonded to a nitrogen atom.
Question 4
True or False: In a eukaryotic cell, the organelles called peroxisomes serve the
purpose of digesting macromolecules.
Answer: False
Rationale: Lysosomes digest macromolecules. Peroxisomes primarily break
down fatty acids and detoxify harmful substances.
,Question 5
True or False: Carbon dioxide has a linear molecular shape AND has a bond
angle of 120°.
Answer: False
Rationale: Carbon dioxide (CO₂) is linear, but its bond angle is 180°, not 120°.
Question 6
Of the following, __________ is not a property of carbon.
Forming ionic bonds
Forming cyclic structures
Forming multiple bonds
Forming bonds with oxygen
Bonding in long chains
Answer: Forming ionic bonds
Rationale: Carbon predominantly forms covalent bonds, not ionic bonds.
Question 7
Which of the following is an element not typically found in living organisms?
Br
Ca
H
S
Na
Answer: Br (Bromine)
Rationale: Hydrogen (H), sulfur (S), sodium (Na), and calcium (Ca) are
commonly found in living organisms. Bromine is not typically considered a major
biological element.
, Question 8
pts
is a functional group found in carbohydrates.
Esters
Thiols
Carboxylic acids
Alcohols
Amines
ALCOHOLS
Question 9
pts
The following functional group is an example of .
