Chapter 01: Cellular Biology
1. A student is observing a cell under the microscope. It is observed to have
supercoiled DNAwith 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 prokaryotecontains 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
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 secretionallows 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 thegenetic 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 thecell’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
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 markscells 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 support the diagnosis of metastatic cancer?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 themto travel or metastasize.
REF: p. 10
7. Which form of cell communication is used to relate to other cells in direct physical
contact? a. Celljunction
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 junctionsare associated with cellular communication.
REF: p. 11
8. Pancreatic beta cells secrete insulin, which inhibits secretion of glucagon from
neighboring alphacells. This action is an example of which of the following signaling
types? a. Paracrine
b. Autocrine
c. Neurohormonal
d. Hormonal
ANS: A
Paracrine signaling involves the release of local chemical mediators that are quickly
taken up, destroyed, or immobilized, as in the case of insulin and the inhibition of the
secretion of glucagon.None of the other options involve signaling that is associated
with a local chemical mediator like insulin.
REF: p. 12
9. In cellular metabolism, each enzyme has a high affinity for a:
a. solute.
b. substrate.
c. receptor.
