1. Which of the following best describes the role of DNA
polymerase during DNA replication?
a) Synthesizes RNA primers.
b) Unwinds the DNA double helix.
c) Adds nucleotides to the growing DNA strand.
d) Binds to the promoter region of the DNA.
ANS: c) Adds nucleotides to the growing DNA strand.

, Rationale: DNA polymerase is the enzyme responsible for
adding nucleotides to the 3' end of the newly synthesized DNA
strand during replication.
2. Which of the following is NOT a function of the smooth
endoplasmic reticulum?
a) Lipid synthesis.
b) Protein synthesis.
c) Detoxification of drugs.
d) Calcium ion storage.
ANS: b) Protein synthesis.
Rationale: Protein synthesis is a function of the rough
endoplasmic reticulum, which is studded with ribosomes, unlike
the smooth endoplasmic reticulum.
Fill-in-the-Blank Questions
3. The process by which a cell engulfs large particles or whole
cells, either as a defense mechanism or as a means to obtain food,
is known as __________.
ANS: Phagocytosis.
Rationale: Phagocytosis is a form of endocytosis where a cell
engulfs large particles or cells.

,4. In eukaryotic cells, the ___________ is the organelle
responsible for ATP production.
ANS: Mitochondrion.
Rationale: The mitochondrion, often referred to as the
powerhouse of the cell, is where ATP production occurs through
cellular respiration.
True/False Questions
5. Enzymes are consumed in the reactions they catalyze.
ANS: False.
Rationale: Enzymes are not consumed in reactions; they act
as catalysts and can be used repeatedly.
6. Osmosis requires energy input from the cell.
ANS: False.
Rationale: Osmosis is a passive process that does not require
energy input from the cell.
Multiple Response Questions
7. Which of the following structures are part of the
endomembrane system? (Select all that apply)
a) Golgi apparatus.
©2025
, b) Mitochondria.
c) Endoplasmic reticulum.
d) Lysosomes.
ANSs: a) Golgi apparatus, c) Endoplasmic reticulum, d)
Lysosomes.
Rationale: The endomembrane system includes the Golgi
apparatus, endoplasmic reticulum, and lysosomes, but not
mitochondria.
8. Which of the following are products of the light-dependent
reactions of photosynthesis? (Select all that apply)
a) Oxygen.
b) NADPH.
c) ATP.
d) Glucose.
ANSs: a) Oxygen, b) NADPH, c) ATP.
Rationale: The light-dependent reactions produce oxygen,
NADPH, and ATP; glucose is produced in the Calvin cycle, not
the light-dependent reactions.
Additional Questions
9. Which enzyme is responsible for synthesizing RNA from a
DNA template during transcription?
