1. Which cellular adaptation is characterized by the replacement of one mature cell type by
another, less mature cell type?
A. Atrophy
B. Metaplasia
C. Dysplasia
D. Hyperplasia
Answer: B
Conceptual Explanation: Metaplasia is a reversible replacement of one mature cell type
by another, often in response to chronic irritation.
2. In the context of cellular injury, what is the primary mechanism by which carbon monoxide
causes tissue hypoxia?
A. Binding to hemoglobin with a higher affinity than oxygen
B. Inhibition of ATP production in the mitochondria
C. Direct destruction of red blood cell membranes
,D. Stimulation of excessive erythropoietin production
Answer: A
Conceptual Explanation: Carbon monoxide binds to hemoglobin with an affinity 200
times greater than oxygen, preventing oxygen transport.
3. Which process describes the programmed cell death that does not elicit an inflammatory
response?
A. Necrosis
B. Autolysis
C. Karyolysis
D. Apoptosis
Answer: D
Conceptual Explanation: Apoptosis is a distinct type of cell death that is programmed and
neat, avoiding the leakage of cellular contents and subsequent inflammation.
4. What is the pathophysiological significance of increased levels of troponin I and T in the
bloodstream?
A. Renal tubular necrosis
B. Myocardial cell death
C. Skeletal muscle strain
D. Hepatic encephalopathy
, Answer: B
Conceptual Explanation: Troponins are regulatory proteins in cardiac muscle; their
presence in serum indicates myocardial injury or infarction.
5. Which genetic concept explains why some individuals with a dominant gene do not express
the associated phenotype?
A. Incomplete penetrance
B. Variable expressivity
C. Polygenic inheritance
D. Genomic imprinting
Answer: A
Conceptual Explanation: Incomplete penetrance occurs when individuals who carry a
disease-causing genotype do not exhibit the disease phenotype.
6. What is the primary immunological mechanism involved in a Type I hypersensitivity
reaction?
A. IgE binding to mast cells and basophils
B. T-cell mediated delayed reaction
C. Antigen-antibody complex deposition
D. IgG-mediated cytotoxic response
Answer: A
