# SECTION I: Cellular Function & Genetics (Questions 1-15)
**1.** A 45-year-old patient with chronic alcoholism is admitted with
confusion and ataxia. Serum magnesium is 1.0 mg/dL (normal 1.8-2.5).
Which cellular process is most directly impaired?
- A) Sodium-potassium pump function
- B) ATP production in mitochondria
- C) DNA replication in the nucleus
- D) Ribosomal protein synthesis
**Answer: B**
**Rationale:** Magnesium is a cofactor for ATP production.
Hypomagnesemia impairs oxidative phosphorylation and mitochondrial
function, leading to neurological symptoms.
**2.** A biopsy of a chronically inflamed wound shows cells with
enlarged nuclei and prominent nucleoli. This change is best described as:
- A) Metaplasia
- B) Dysplasia
- C) Hypertrophy
- D) Hyperplasia
,3|Page
**Answer: B**
**Rationale:** Dysplasia refers to disordered cellular growth with
nuclear enlargement, hyperchromasia, and increased mitotic figures,
often seen in chronic inflammation or precancerous lesions.
**3.** Which statement about apoptosis is correct?
- A) It triggers an inflammatory response
- B) It is mediated by caspases
- C) It results in cell swelling and lysis
- D) It is always pathologic
**Answer: B**
**Rationale:** Apoptosis is programmed cell death mediated by
caspases, does not trigger inflammation, and can be physiologic (e.g.,
embryogenesis) or pathologic.
**4.** A genetic mutation results in a nonfunctional tumor suppressor
gene. Which is most likely to occur?
- A) Increased apoptosis
- B) Uncontrolled cell division
- C) Enhanced DNA repair
- D) Reduced angiogenesis
, 4|Page
**Answer: B**
**Rationale:** Tumor suppressor genes (e.g., p53, Rb) normally inhibit
cell cycle progression. Loss of function removes growth restraints,
promoting neoplasia.
**5.** During hypoxia, a cell switches to anaerobic metabolism. This
leads to:
- A) Increased ATP production
- B) Decreased intracellular pH
- C) Alkalosis of the cytosol
- D) Enhanced oxidative phosphorylation
**Answer: B**
**Rationale:** Anaerobic glycolysis produces lactic acid, decreasing
intracellular pH and impairing cellular function.
**6.** A patient has a mutation in the CFTR gene. Which cellular
process is directly affected?
- A) Chloride ion transport
- B) Sodium reabsorption
- C) Potassium channel function
- D) Calcium signaling
