,Q1. A researcher is studying a novel protein that, when mutated, prevents the release of cytochrome c from
mitochondria in response to cellular stress. Which of the following processes would be most directly impaired
by this mutation?
A. Necrosis
B. Apoptosis via the intrinsic pathway
C. Apoptosis via the extrinsic pathway
D. Autophagy
Correct Answer: B. Apoptosis via the intrinsic pathway
Rationale: Cytochrome c release from mitochondria is a key step in the intrinsic (mitochondrial) pathway of
apoptosis. The extrinsic pathway involves death receptors and does not require mitochondrial cytochrome c.
Necrosis is unregulated cell death, and autophagy is a survival mechanism.
Why Wrong:
A - Necrosis is not dependent on cytochrome c release; it results from severe cellular injury.
C - The extrinsic pathway is initiated by death receptors and does not involve mitochondrial cytochrome c
release.
D - Autophagy is a lysosomal degradation process for recycling cellular components, independent of
cytochrome c.

Q2. In a patient with chronic venous insufficiency, stasis dermatitis develops due to extravasation of
erythrocytes and subsequent breakdown of hemoglobin. Which of the following pigments is primarily
responsible for the characteristic brownish discoloration of the skin in this condition?
A. Bilirubin
B. Hemosiderin
C. Lipofuscin
D. Melanin
Correct Answer: B. Hemosiderin
Rationale: Hemosiderin is an iron-storage pigment derived from hemoglobin breakdown, and its accumulation in
tissues causes brown discoloration. Bilirubin leads to jaundice, lipofuscin is a wear-and-tear pigment, and melanin
is a normal skin pigment.
Why Wrong:
A - Bilirubin causes yellow discoloration (jaundice), not brown discoloration in stasis dermatitis.
C - Lipofuscin is a yellow-brown pigment associated with aging, not specifically with venous stasis.
D - Melanin is responsible for skin color variation but is not derived from hemoglobin breakdown.

Children, 9th Ed., Ch. 5
Q3. A patient presents with recurrent bacterial infections, impaired wound healing, and a history of delayed
separation of the umbilical cord. Laboratory evaluation reveals elevated serum IgE levels and normal
neutrophil counts. Which leukocyte adhesion deficiency is most likely?
A. Leukocyte adhesion deficiency type I (LAD-I)
B. Leukocyte adhesion deficiency type II (LAD-II)
C. Leukocyte adhesion deficiency type III (LAD-III)
D. Chronic granulomatous disease
Correct Answer: B. Leukocyte adhesion deficiency type II (LAD-II)
Rationale: LAD-II is due to a defect in fucosylation, leading to absence of sialyl-Lewis X, the ligand for selectins.
This causes impaired rolling and adhesion, with delayed umbilical cord separation and recurrent infections.
Elevated IgE is characteristic. LAD-I involves 2 integrins, LAD-III involves integrin activation, and chronic
Page 3
, granulomatous disease involves NADPH oxidase.
Why Wrong:
A - LAD-I is characterized by defective 2 integrins (CD18), leading to impaired firm adhesion, but does not typically
present with elevated IgE.
C - LAD-III involves defective integrin activation and also presents with bleeding tendency due to platelet dysfunction.
D - Chronic granulomatous disease results from defective NADPH oxidase, causing recurrent infections with granuloma
formation, not elevated IgE.

Q4. A 45-year-old patient with a history of hypertension and diabetes presents with sudden onset of severe
chest pain radiating to the back, and a blood pressure difference of 30 mm Hg between arms. Imaging reveals
a tear in the aortic intima with blood entering the media. Which of the following is the most likely underlying
mechanism contributing to this condition?
A. Cystic medial degeneration due to loss of smooth muscle cells and elastic fibers
B. Atherosclerotic plaque rupture causing intramural hemorrhage
C. Vasculitis of the vasa vasorum leading to medial necrosis
D. Traumatic disruption of the aortic wall layers
Correct Answer: A. Cystic medial degeneration due to loss of smooth muscle cells and elastic fibers
Rationale: Aortic dissection often occurs due to cystic medial degeneration, characterized by loss of smooth muscle
cells and elastic fibers, weakening the aortic wall. Hypertension and aging are common predisposing factors.
Atherosclerosis can contribute but is not the primary mechanism. Vasculitis and trauma are less common causes.
Why Wrong:
B - Atherosclerotic plaque rupture typically causes thrombosis or embolism, not dissection into the media.
C - Vasculitis of the vasa vasorum can cause aortic aneurysm but is a less common cause of dissection.
D - Trauma can cause aortic rupture or dissection but is not the underlying mechanism in this clinical
scenario.

Q5. A researcher is investigating a tumor that shows loss of heterozygosity at the RB1 locus, and the tumor
cells exhibit high levels of phosphorylated retinoblastoma protein (pRb). Which of the following is the most
likely consequence of this genetic alteration?
A. Increased activity of E2F transcription factors leading to cell cycle progression
B. Constitutive activation of p53-mediated apoptosis
C. Enhanced DNA repair capacity
D. Inhibition of cyclin-dependent kinase activity
Correct Answer: A. Increased activity of E2F transcription factors leading to cell cycle progression
Rationale: Loss of heterozygosity at RB1 leads to loss of functional pRb. pRb normally binds and inhibits E2F
transcription factors; when pRb is absent or inactivated, E2F is free to promote cell cycle progression.
Phosphorylated pRb is inactive, further contributing to unregulated proliferation.
Why Wrong:
B - p53-mediated apoptosis is typically activated by cellular stress, but loss of RB1 does not directly cause
constitutive p53 activation.
C - Loss of RB1 impairs cell cycle control, not DNA repair capacity.
D - Cyclin-dependent kinase activity is increased, not inhibited, due to loss of pRb regulation.
