DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+||
Which of the following molecules is likely to accumulate in any
dead or dying tissues?
a. Calcium
b. Uric acid
c. Melanin
d. Protein - ANSWER- a. Calcium
Rationale: When calcium pumps fail due to mitochondrial
injury, calcium accumulates in the cytoplasm and
contributes to irreversible cellular injury and cell death.
Why is carbon monoxide exposure a life-threatening condition?
a. Carbon monoxide causes the release of toxic amounts of iron
from the tissues.
,2|Page
b. Inhalation of carbon monoxide interferes with oxygen
diffusion in the lungs.
c. Carbon dioxide removal from the tissues is inhibited.
d. Carbon monoxide binds to hemoglobin and prevents normal
oxygen transport to tissues. - ANSWER- d. Carbon monoxide
binds to hemoglobin and prevents normal oxygen transport to
tissues.
Which of the following molecules accumulates in liver cells as a
result of alcohol abuse?
a. Fat (lipids)
b. Water
c. Iron
d. Protein - ANSWER- a. Fat (lipids)
What are the primary factors contributing to oncosis from
hypoxic injury?
a. Increase in ATP production and potassium movement out of
the cell
b. Accumulation of lipids and pigments in the cell
c. Injury to the endoplasmic reticulum and Golgi apparatus
,3|Page
d. Decrease in ATP production and sodium movement into the
cell - ANSWER- d. Decrease in ATP production and sodium
movement into the cell
Pathologic hyperplasia can lead to:
a. phagocytosis.
b. stem cell activation.
c. enlargement of the uterus.
d. metaplasia. - ANSWER- d. metaplasia.
Which of the following is a form of metaplasia that can occur in
the human body?
a. Epithelial cells of the bronchial lining are replaced with
collagenous connective tissue.
b. Adipose cells are replaced by cells that cannot store lipids.
c. Squamous epithelial cells of the esophageal lining are
replaced by glandular cells similar to those lining the stomach.
d. Liver cells are replaced by squamous epithelial cells. -
ANSWER- c. Squamous epithelial cells of the esophageal lining
are replaced by glandular cells similar to those lining the
stomach.

Free radicals directly injure cells by each of the following
mechanisms except:
a. DNA fragmentation.
b. lipid peroxidation.
c. activation of lysosomal enzymes.
d. alteration of proteins. - ANSWER- c. activation of lysosomal
enzymes.
Restoration of oxygen to oxygen-deprived tissues results in:
a. chemical injury.
b. establishment of normal cell metabolism.
c. reperfusion injury.
d. hypoxic injury. - ANSWER- c. reperfusion injury.
The process of cellular atrophy may be accomplished through
which of the following processes?
a. Decreased cell division
b. Loss of fluid
