,Section A - Cellular Adaptation Injury AND Death
Q1.
A cell exposed to chronic hypoxic stress upregulates HIF-1, leading to a shift from
oxidative phosphorylation to glycolysis. Which molecular consequence most directly
explains the cell's survival advantage?
A. Increased mitochondrial reactive oxygen B. Upregulation of glucose transporters and
species (ROS) production enhances glycolytic enzymes maintains ATP
antioxidant defenses. production despite low oxygen.
C. Inhibition of apoptosis by directly blocking D. Stabilization of p53 promotes cell cycle
caspase-9 activation. arrest and DNA repair.
Correct: B - Upregulation of glucose transporters and glycolytic enzymes maintains ATP
production despite low oxygen.
Rationale:HIF-1± is a master regulator of the hypoxic response; it transcriptionally
upregulates genes like GLUT1 and glycolytic enzymes, allowing ATP generation without
oxygen. While HIF-1 can inhibit apoptosis and promote survival, its primary role in hypoxia is
metabolic adaptation. Increased ROS would worsen oxidative stress, and p53 stabilization
typically promotes apoptosis, not survival.
Q2.
In acute inflammation, neutrophil extravasation involves a sequence of adhesion events.
Which molecular interaction is primarily responsible for firm adhesion and arrest on the
endothelium?
A. L-selectin binding to sialyl-Lewis B. Integrin (LFA-1) binding to ICAM-1 on
X-modified glycoproteins. activated endothelium.
C. P-selectin binding to PSGL-1. D. Platelet-activating factor (PAF) binding to
its receptor on neutrophils.
Correct: B - Integrin (LFA-1) binding to ICAM-1 on activated endothelium.
Rationale:Firm adhesion and arrest are mediated by integrins (such as LFA-1) on neutrophils
binding to ICAM-1 on endothelial cells. Selectins mediate the initial rolling, and PAF activates
integrins but does not directly mediate adhesion.
Q3.
A tissue injury triggers the release of arachidonic acid from membrane phospholipids.
Which enzyme is the primary target of nonsteroidal anti-inflammatory drugs (NSAIDs) to
reduce prostaglandin synthesis?
A. Phospholipase A2 B. Lipoxygenase
Page 3
, Section A - Cellular Adaptation Injury AND Death
C. Cyclooxygenase (COX) D. Cytochrome P450 epoxygenase
Correct: C - Cyclooxygenase (COX)
Rationale:NSAIDs inhibit cyclooxygenase (COX) enzymes, which convert arachidonic acid
into prostaglandins and thromboxanes. Phospholipase A2 releases arachidonic acid but is not
the direct target of NSAIDs; lipoxygenase produces leukotrienes, and epoxygenase produces
epoxides.
Q4.
A patient with chronic heart failure develops peripheral edema. Which combination of
hemodynamic forces most directly explains the fluid shift into the interstitial space?
A. Increased capillary hydrostatic pressure B. Decreased capillary hydrostatic pressure
and decreased plasma oncotic pressure. and increased interstitial oncotic pressure.
C. Increased plasma oncotic pressure and D. Lymphatic obstruction and increased
decreased interstitial hydrostatic pressure. plasma oncotic pressure.
Correct: A - Increased capillary hydrostatic pressure and decreased plasma oncotic
pressure.
Rationale:In heart failure, increased venous pressure raises capillary hydrostatic pressure,
favoring filtration. Additionally, reduced hepatic synthesis of albumin (due to congestion)
lowers plasma oncotic pressure, further promoting edema. The other combinations either
oppose edema or are not typical.
Q5.
A biopsy from a tumor shows cells with a high nuclear-to-cytoplasmic ratio, prominent
nucleoli, and numerous atypical mitoses. Which term best describes this microscopic
appearance?
A. Dysplasia B. Anaplasia
C. Metaplasia D. Hypertrophy
Correct: B - Anaplasia
Rationale:Anaplasia refers to a lack of differentiation, characterized by pleomorphism,
hyperchromatic nuclei, high N:C ratio, and atypical mitoses, indicating malignancy. Dysplasia
is a preneoplastic change with less severe atypia; metaplasia is a reversible change from one
adult cell type to another; hypertrophy is an increase in cell size.
Q6.
A patient with a BRCA1 mutation is at increased risk for breast and ovarian cancer. Which
DNA repair pathway is most directly impaired by this mutation?
