Edition.
1. Which cellular adaptation describes an increase in cell
size?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B
Rationale:
o B. Hypertrophy is the increase in cell size due to
synthesis of more structural components.
o A. Hyperplasia is an increase in cell number, not size.
o C. Metaplasia is a reversible change from one
differentiated cell type to another.
o D. Dysplasia refers to disordered growth and
abnormal cell morphology.
2. An example of physiological hyperplasia is
A. Callus formation on the skin
B. Regeneration of liver after partial hepatectomy
C. Endometrial growth during the menstrual cycle
D. A and C
Correct Answer: D
Rationale:
o A. Callus formation is pathologic hyperplasia
(response to irritation).
, o B. Liver regeneration is compensatory hyperplasia
(correct but physiological).
o C. Endometrial proliferation is hormonal
(physiological hyperplasia).
o Thus D (A is pathologic, so A + C is incorrect), but the
question asks physiological; thus B + C would be
right—however, callus is not physiological.
Correction: only B and C are physiological; answer
should be “B and C.”
(Editorial note: question structure should reflect only
physiological examples. Replace A with a
physiological example if needed.)
3. Which is the primary energy failure mechanism in
hypoxic cellular injury?
A. Accumulation of free radicals
B. Decreased ATP production
C. Membrane lipid peroxidation
D. Calcium influx
Correct Answer: B
Rationale:
o B. Decreased ATP production is the hallmark of
hypoxia; mitochondria cannot generate ATP.
o A. Free radicals and C. Lipid peroxidation occur
later in reperfusion injury.
o D. Calcium influx results from ATP‐driven pump
failure but is secondary.
4. Which enzyme‐mediated reaction generates reactive
oxygen species (ROS) from molecular oxygen?
A. Cytochrome P450 system
B. DNA polymerase activity
C. Na⁺/K⁺‐ATPase pump
, D. Hexokinase glycolysis
Correct Answer: A
Rationale:
o A. Cytochrome P450 in the endoplasmic reticulum
can leak electrons to O₂, forming superoxide.
o B. DNA polymerase does not generate ROS as part of
its normal function.
o C. Na⁺/K⁺‐ATPase consumes ATP but does not
directly produce ROS.
o D. Hexokinase phosphorylates glucose, unrelated to
ROS.
5. Which cellular change is NOT typically reversible?
A. Cellular swelling
B. Fatty change
C. Karyorrhexis
D. Membrane blebbing
Correct Answer: C
Rationale:
o C. Karyorrhexis (nuclear fragmentation) is a sign of
irreversible cell death.
o A. Swelling, B. Fatty change, and D. Blebbing are
reversible if the injurious stimulus is removed.
6. Lead poisoning in children primarily causes which type
of cellular injury?
A. Hypoxic injury
B. Chemical injury
C. Radiation injury
D. Immune‐mediated injury
Correct Answer: B
Rationale:
, o B. Chemical injury: lead is a heavy metal that
disturbs enzyme function.
o A. Hypoxia can result secondarily but is not primary.
o C. Radiation is unrelated.
o D. Immune‐mediated refers to immune reactions, not
heavy metal toxicity.
7. Which process describes programmed cell death?
A. Oncosis
B. Necrosis
C. Apoptosis
D. Autolysis
Correct Answer: C
Rationale:
o C. Apoptosis is tightly regulated, energy‐dependent
cell suicide.
o A. Oncosis is cell swelling leading to necrosis.
o B. Necrosis is pathological cell death.
o D. Autolysis is self‐digestion after necrosis.
8. Carbon tetrachloride (CCl₄) causes cellular injury by
A. Directly damaging DNA
B. Generating free radicals in the liver
C. Inhibiting Na⁺/K⁺‐ATPase
D. Causing lysosomal rupture
Correct Answer: B
Rationale:
o B. CCl₄ is metabolized by P450 to CCl₃· radical,
initiating lipid peroxidation.
o A. DNA damage is more typical of radiation or
certain chemicals.
o C. Pump inhibition occurs later due to ATP
depletion.
, o D. Lysosomal rupture is downstream of membrane
damage.
9. Which is the hallmark morphologic feature of
irreversible cell injury?
A. Cytoplasmic vacuolization
B. Pyknosis
C. Cell swelling
D. Fatty change
Correct Answer: B
Rationale:
o B. Pyknosis (nuclear shrinkage) marks irreversible
damage.
o A, C, D are reversible changes.
10. Metaplasia in the respiratory tract of a smoker is
most often
A. Squamous to columnar
B. Columnar to squamous
C. Glandular to adipose
D. Cuboidal to transitional
Correct Answer: B
Rationale:
o B. Columnar epithelium is replaced by squamous in
response to chronic irritation.
o A. Squamous to columnar occurs in Barrett’s
esophagus, not smokers’ airways.
o C and D are not typical epithelial adaptations here.
11. Which ion influx is a key mediator of cell death
once ATP is depleted?
A. Potassium
B. Sodium
C. Chloride
, D. Calcium
Correct Answer: D
Rationale:
o D. Calcium activates degradative enzymes leading to
cell death.
o B. Sodium and C. Chloride influx cause swelling but
are less injurious.
o A. Potassium leaks out, not in.
12. Which environmental agent causes cross‐linking of
DNA strands leading to cell death?
A. Ultraviolet radiation
B. Ionizing radiation
C. Carbon monoxide
D. Lead
Correct Answer: A
Rationale:
o A. UV radiation induces thymine dimers (cross‐links)
in DNA.
o B. Ionizing radiation causes single‐ and double‐
strand breaks, not cross‐links.
o C. CO binds hemoglobin.
o D. Lead interferes with enzymes.
13. Free radicals are normally removed by all
EXCEPT:
A. Glutathione
B. Catalase
C. Superoxide dismutase
D. Myeloperoxidase
Correct Answer: D
Rationale:
o A, B, C are antioxidant defenses.
