1. Cellular Injury
Q1. Which cellular adaptation occurs in response to
increased workload?
A. Atrophy
B. Hypertrophy
C. Metaplasia
D. Dysplasia
,Answer: B
Increased cell size due to workload
Common in cardiac and skeletal muscle
Q2. Hypoxia primarily leads to:
A. Increased ATP production
B. Cellular swelling
C. DNA repair
D. Increased mitosis
Answer: B
ATP depletion causes sodium-potassium pump failure
Water enters cell → swelling

A. Ribosome detachment
B. Mitochondrial damage
C. Fat accumulation
D. Glycogen increase
,Answer: B
Mitochondrial dysfunction is irreversible
Leads to necrosis

Answer: B
Energy-dependent process
No inflammation
Q5. Free radicals damage cells by:
A. Increasing oxygen delivery
B. Lipid peroxidation
C. DNA stabilization
, D. Protein synthesis
Answer: B
Damages cell membranes
Leads to oxidative stress
2. Inflammation & Immunity
Q6. Histamine primarily causes:
A. Vasoconstriction
B. Increased vascular permeability
C. RBC production
D. Platelet aggregation
Answer: B
Released from mast cells
Causes edema
Q7. The first leukocytes at infection site are:
