SECTION 1 — CELLULAR BIOLOGY, ADAPTATION, INJURY & DEATH
Questions 1–20
Q1
A patient with chronic hypertension develops enlargement of the left ventricular myocardium.
Which cellular adaptation best explains this finding?
,A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B. Hypertrophy
Rationale: Hypertrophy is an increase in cell size caused by increased workload. Cardiac
myocytes have limited proliferative capacity, so chronic pressure overload primarily produces
hypertrophy rather than hyperplasia.
Q2
Which cellular process involves programmed, energy-dependent cell death without significant
surrounding inflammation?
A. Necrosis
B. Apoptosis
C. Autolysis
D. Ischemia
Correct Answer: B. Apoptosis
Rationale: Apoptosis is regulated cell death involving caspase activation and cellular
fragmentation. Unlike necrosis, apoptosis generally does not produce substantial inflammatory
leakage into surrounding tissue.
Q3
A patient experiences temporary renal ischemia during surgery, followed by restoration of blood
flow. Which cellular injury is most likely to occur initially?
A. Decreased ATP production
B. Increased oxidative phosphorylation
C. Increased intracellular calcium removal
D. Increased protein synthesis
Correct Answer: A. Decreased ATP production
Rationale: Ischemia reduces oxygen delivery and impairs mitochondrial oxidative
phosphorylation, decreasing ATP production. ATP depletion disrupts ion pumps and cellular
homeostasis.
Q4
Which organelle is primarily responsible for producing ATP through oxidative phosphorylation?
,A. Lysosome
B. Ribosome
C. Mitochondrion
D. Golgi apparatus
Correct Answer: C. Mitochondrion
Rationale: Mitochondria generate most cellular ATP through oxidative phosphorylation.
Lysosomes digest cellular material, ribosomes synthesize proteins, and the Golgi apparatus
modifies and packages proteins.
Q5
A patient has chronic gastroesophageal irritation resulting in replacement of normal esophageal
epithelium with a different epithelial phenotype. Which adaptation is being demonstrated?
A. Atrophy
B. Hyperplasia
C. Metaplasia
D. Hypertrophy
Correct Answer: C. Metaplasia
Rationale: Metaplasia is a reversible substitution of one differentiated cell type for another
better suited to chronic stress. Persistent metaplasia can increase the risk of dysplasia and
malignancy depending on the tissue and stimulus.
Q6
Which finding most directly indicates cellular membrane injury?
A. Increased intracellular potassium
B. Leakage of intracellular enzymes
C. Increased ATP production
D. Increased protein synthesis
Correct Answer: B. Leakage of intracellular enzymes
Rationale: Loss of membrane integrity permits intracellular proteins and enzymes to escape into
extracellular fluid and blood. Clinically, elevated troponin and aminotransferases can reflect this
principle in specific tissues.
Q7
A patient with severe hypoxia develops cellular swelling. Which mechanism most directly causes
this change?
, A. Increased sodium-potassium pump activity
B. Failure of ATP-dependent ion transport
C. Increased mitochondrial ATP production
D. Increased intracellular protein degradation
Correct Answer: B. Failure of ATP-dependent ion transport
Rationale: ATP depletion impairs the sodium-potassium ATPase, causing intracellular sodium
and water accumulation. Cellular swelling is an early, potentially reversible manifestation of
injury.
Q8
Which type of cellular adaptation is characterized by an increase in the number of cells?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
Correct Answer: B. Hyperplasia
Rationale: Hyperplasia involves increased cell number through proliferation. Hypertrophy
instead represents increased cell size.
Q9
A patient with prolonged immobilization develops marked skeletal muscle wasting. Which
process best explains this finding?
A. Atrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
Correct Answer: A. Atrophy
Rationale: Disuse decreases protein synthesis and increases protein degradation, producing
muscle atrophy. Restoration of activity can partially reverse the process if irreversible injury has
not occurred.
Q10
A patient develops myocardial infarction after prolonged coronary artery occlusion. Which type
of cell death is most characteristic of the affected myocardium?
A. Apoptosis
B. Coagulative necrosis
