Chapter 01: Cellular Biology
Huether & McCance: Understanding Pathophysiology, 6th Edition
MULTIPLE CHOICES
1. A student is observing a cell under the microscope. It is observed to have supercoiled
DNA with 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
nucleus; thus, the nucleus should be observed. A single circular chromosome called a prokaryote
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 describing when an isolated cell absorbs oxygen and uses it to transform nutrients to
energy?
a. Metabolic absorption
b. Communication
c. Secretion
A+ Page 1
,Created By: A Solution
d. Respiration
ANS: D
The cell’s ability to absorb oxygen is referred to as respiration while its communication ability
involves maintenance of a steady dynamic state, metabolic absorption provides nutrition, and
secretion 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 the 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 ribonucleic
acid, most of the DNA, and DNA-binding proteins, is the nucleolus, which is located within the
cell’s nucleus. Mitochondria is associated with cellular respiration, while ribosomes are involved
with protein manufacturing. 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 layer itself?
a. Peripheral membrane proteins
b. Integral membrane proteins
c. Glycoproteins
A+ Page 2
,Created By: A Solution
d. Cell adhesion molecules
ANS: B
Proteins directly attached to the membrane bilayer can be removed by the action of integral
membrane proteins that dissolve the bilayer. Peripheral membrane proteins reside at the surface
while cell adhesion molecules are on the outside of the membrane. Glycoprotein marks cells and
does not float.
REF: p. 7
5. Which of the following can bind to plasma membrane receptors?
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.
REF: p. 9
6. A nurse is reviewing a report from a patient with metastatic cancer. What alternation in
the extracellular matrix would suNpUpoRrtSthIeNdGiaTgnBo.siCs ofMmetastatic cancer?
a. Decreased fibronectin
b. Increased collagen
c. Decreased elastin
d. Increased glycoproteins
A+ Page 3
, Created By: A Solution
ANS: A
Only a reduced amount of fibronectin is found in some types of cancerous cells, allowing them
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 tight
junctions are associated with cellular communication.
REF: p. 11
8. Pancreatic beta cells secrete insulin, which inhibits secretion of glucagon from
neighboring alpha cells. This action is an example of which of the following signaling types?
a. Paracrine
b. Autocrine
c. Neurohormonal
d. Hormonal
ANS: A
