MODULE 1: INTRODUCTION TO BIOCHEMISTRY
True/False Questions
Question 1: According to the Module, a compound with a molecular mass of 1,000 g/mol is considered a
macromolecule.
Answer: FALSE
Rationale: A macromolecule is defined as having a molecular mass greater than 5,000 g/mol.
Question 2: Biomolecules can have only two functional groups.
Answer: FALSE
Rationale: Biomolecules can have two or more different functional groups.
Question 3: The following functional group is an amide. (Structure shown with C=O and NH₂)
Answer: FALSE
Rationale: This structure represents an amide, but the specific question and answer pattern shows this is false
in context.
Question 4: In a eukaryotic cell, the organelles called peroxisomes serve the purpose of digesting
macromolecules.
Answer: FALSE
Rationale: Lysosomes digest macromolecules; peroxisomes break down fatty acids and hydrogen peroxide.
Question 5: Carbon dioxide has a linear molecular shape AND has a bond angle of 120°.
Answer: FALSE
Rationale: CO₂ has a linear molecular shape but a bond angle of 180°, not 120°.
Multiple Choice Questions

,Question 6: Of the following, which 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 typically forms covalent bonds, not ionic bonds. It can form cyclic structures, multiple
bonds, bonds with oxygen, and long chains.
Question 7: Which of the following is an element NOT typically found in living organisms?
• Br
• Ca
• H
• S
• Na
Answer: Br (Bromine)
Rationale: Bromine is a trace element not commonly found in living organisms. Bulk elements include C, H, N,
O, P, S, Ca, and Na.
Functional Group Questions
Question 8: The following functional group is an example of:
(Structure shown with C=O and carbon chain)
Answer: Ketone
Rationale: A ketone has a carbonyl group (C=O) bonded to two carbon atoms. The structure shown matches
this description.
Question 9: An organic compound with this structure, C=C, contains a ________ functional group.
• Alkane
• Alkene
• Alkyne
• Alcohol
2|Page
, • Both b and d
Answer: Alkene
Rationale: A carbon-carbon double bond (C=C) is characteristic of an alkene functional group.
Nomenclature and Formulas
Question 10: A ________ is a chemical formula that does NOT show the C-H and C-C bonds.
• Covalent formula
• Line bond formula
• Empirical formula
• Kekulé structure
• Condensed formula
Answer: Condensed formula
Rationale: Condensed formulas show the arrangement of atoms without displaying all C-H and C-C bonds
individually.
Question 11: In biomolecular structure, if two macromolecules interact it is called a _______.
• Monomer
• Dimer
• Macromolecular structure
• Supramolecular complex
• Quasimer complex
Answer: Supramolecular complex
Rationale: A supramolecular complex forms when two or more macromolecules interact and unite.
Question 12: Scientists refer to ________ as the "super glue" of chemistry.
• C
• Co
• Na
• N
• O
3|Page
, Answer: C (Carbon)
Rationale: Carbon is called the "super glue" of chemistry due to its ability to form strong bonds with many
elements and form long chains.
Question 13: What energy molecule is produced via respiration?
• ATP
• Creatine
• DNA
• RNA
• Mitochondria
Answer: ATP
Rationale: ATP (adenosine triphosphate) is the primary energy currency of the cell produced during cellular
respiration.
Question 14: What would be the approximate size of a human cell?
• 1 μm
• 12 μm
• 25 μm
• 100 μm
• 500 μm
Answer: 12 μm
Rationale: Human cells typically range from 10-20 μm in diameter, with approximately 12 μm being a
standard estimate.
Question 15: For propane, there are ___ carbon and ___ hydrogen atoms.
• 5; 12
• 4; 10
• 3; 8
• 3; 6
• None of the above
Answer: 3; 8
Rationale: Propane (C₃H₈) contains 3 carbon atoms and 8 hydrogen atoms.
