MULTIPLE CHOICES
1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA
wi th histones. Which of the following would also be observed by the student?
a. A single circular chromosome
b. A nucleus
c. Free-floating nuclear material
d. No organelles
ANS: B
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its
nu cleus; thus, the nucleus should be observed. A single circular chromosome called a pro
kary ote contains free-floating nuclear material but has no organelles.
REF: p. 2
2. A nurse is instructing the staff about cellular functions. Which cellular function is the nurse
de scribing when an isolated cell absorbs oxygen and uses it to transform nutrients to energ
y?
a. Metabolic absorption
b. Communication
c. Secretion
d. Respiration
ANS: D
Test Bank Page 2
, Test BankUnderstandingPathophysiology7th Edition
The cell’s ability to absorb oxygen is referred to as respiration while its communication ability
in volves maintenance of a steady dynamic state, metabolic absorption provides nutrition, and
secr etion allows for the synthesizing of new substances.
REF: p. 2
3. A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of
th e genetic information be contained?
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm
ANS: C
The region of the cell that contains genetic material, including a large amount of ribonucleica
c id, most of the DNA, and DNA-
binding proteins, is the nucleolus, which is located withinthe cell’s nucleus. Mitochondria is
a ssociated with cellular respiration, while ribosomes are involved with protein manufactur
ing. Cytoplasm is a fluid filling that is a component of the cell.
REF: p. 2
4. Which of the following can remove proteins attached to the cell’s bilayer by dissolving the
la yer itself?
a. Peripheral membrane proteins
b. Integral membrane proteins
c. Glycoproteins
d. Cell adhesion molecules
ANS: B
Proteins directly attached to the membrane bilayer can be removed by the action of integral
me mbrane proteins that dissolve the bilayer. Peripheral membrane proteins reside at the su
rface while cell adhesion molecules are on the outside of the membrane. Glycoprotein mark
s cells a nd does not float.
REF: p. 7
5. Which of the following can bind to plasma membrane receptors?
Test Bank Page 3
, Test BankUnderstandingPathophysiology7th Edition
a. Oxygen
b. Ribosomes
c. Amphipathic lipids
d. Ligands
ANS: D
Ligands are the only specific molecules that can bind with receptors on the cell membrane.

6. A nurse is reviewing a report from a patient with metastatic cancer. What alternation in the
ex tracelularmatrixVwouldVsuNp pUoRr t St hIe Nd Gi a T

s ofMm etastatic cancer?
P
a. Decreased fibronectin
b. Increased collagen
c. Decreased elastin
d. Increased glycoproteins
ANS: A
Only a reduced amount of fibronectin is found in some types of cancerous cells, allowing
th em to travel or metastasize.
REF: p. 10
7. Which form of cell communication is used to relate to other cells in direct physical contact?
a. Cell junction
b. Gap junction
c. Desmosome
d. Tight junction
ANS: A
Cell junctions hold cells together and permit molecules to pass from cell to cell.
Gap junctions allow for cellular communication between cells. Neither desmosomes nor tightju nct
ions are associated with cellular communication.
