,Exam Questions
A) Which type of cellular adaptation occurs when cells increase in size to meet in-
creased functional demands?
A) Atrophy
B) Hypertrophy
C) Metaplasia
D) Dysplasia
Rationale: Hypertrophy is the increase in cell size due to increased functional
demand, such as in cardiac muscle during hypertension. Atrophy is cell shrinkage,
metaplasia is cell type change, and dysplasia is abnormal cell growth.
B) What is the primary source of energy for cells under normal physiological condi-
tions?
A) Adenosine triphosphate (ATP)
B) Glucose-6-phosphate
C) Lactic acid
D) Pyruvate
Rationale: ATP is the primary energy currency of cells, produced mainly through
oxidative phosphorylation in mitochondria. Other options are intermediates or
byproducts, not primary energy sources.
C) Which process is characterized by programmed cell death?
A) Necrosis
B) Apoptosis
C) Autophagy
D) Mitosis
Rationale: Apoptosis is a controlled, programmed process of cell death to elimi-
nate damaged or unnecessary cells. Necrosis is uncontrolled, autophagy is cellular
recycling, and mitosis is cell division.

, D) What is the hallmark of acute inflammation?
A) Increased vascular permeability
B) Fibrosis
C) Granuloma formation
D) Chronic lymphocyte infiltration
Rationale: Acute inflammation involves increased vascular permeability, leading
to edema and immune cell migration. Fibrosis and granulomas are features of
chronic inflammation, and lymphocyte infiltration is not specific to acute inflam-
mation.
E) Which cytokine is primarily responsible for inducing fever during inflammation?
A) Interleukin-1 (IL-1)
B) Tumor necrosis factor-alpha (TNF-)
C) Interferon-gamma (IFN-)
D) Interleukin-10 (IL-10)
Rationale: IL-1 acts on the hypothalamus to induce fever during inflammation.
TNF- and IFN- have other roles, and IL-10 is anti-inflammatory.
F) Which immunoglobulin is most abundant in human serum?
A) IgA
B) IgM
C) IgG
D) IgE
Rationale: IgG is the most abundant immunoglobulin in serum, playing a key role
in long-term immunity. IgA is in secretions, IgM is in early responses, and IgE is
in allergic reactions.
G) A point mutation in DNA is most likely to result in what type of genetic alteration?
A) Chromosomal translocation
