MULTIPLE CHOICE ilil
1. A student is observing a cell under the microscope. It is observed to have supercoiled
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
DNA with histones. Which of the following would also be observed by the student?

a. A single circular chromosome ilil ilil ilil
b. A nucleus ilil
c. Free-floating nuclear material ilil ilil
d. No organelles ilil
ANS: i l i l B
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
nucleus; thus, the nucleus should be observed. A single circular chromosome called a
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
prokaryote contains free-floating nuclear material but has no organelles.

2. A nurse is instructing the staff about cellular functions. Which cellular function is the
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
nurse describing when an isolated cell absorbs oxygen and uses it to transform nutrients to
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
energy?
il
a. Metabolic absorption ilil
b. Communication
c. Secretion
d. Respiration
ANS: D ilil
The cell’s ability to absorb oxygen is referred to as respiration while its communication ability
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
involves maintenance of a steady dynamic state, metabolic absorption provides nutrition, and
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
secretion allows for the synthesizing of new substances.

3. A eukaryotic cell is undergoing DNA replication. In which region of the cell would most
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
of the genetic information be contained?
ilil ilil ilil ilil ilil ilil
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm ilil
ANS: C ilil
The region of the cell that contains genetic material, including a large amount of ribonucleic
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
acid, most of the DNA, and DNA-binding proteins, is the nucleolus, which is located
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
within the cell’s nucleus. Mitochondria is associated with cellular respiration, while
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
ribosomes are involved with protein manufacturing. Cytoplasm is a fluid filling that is a
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
component of the cell.

ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
the layer itself?
ilil ilil ilil
a. Peripheral membrane proteins ilil ilil
b. Integral membrane proteins ilil ilil
c. Glycoproteins
d. Cell adhesion molecules ilil ilil
ANS: B ilil
Proteins directly attached to the membrane bilayer can be removed by the action of integral
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
membrane proteins that dissolve the bilayer. Peripheral membrane proteins reside at the
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
surface while cell adhesion molecules are on the outside of the membrane. Glycoprotein
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
marks cells and does not float.

7. Which form of cell communication is used to relate to other cells in direct physical contact?
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
a. Cell junction ilil
b. Gap junction ilil
c. Desmosome
d. Tight junction ilil
ANS: A ilil
Cell junctions hold cells together and permit molecules to pass from cell to cell.
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
Gap junctions allow for cellular communication between cells. Neither desmosomes nor

8. Pancreatic beta cells secrete insulin, which inhibits secretion of glucagon from neighboring
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil il
alpha cells. This action is an example of which of the following signaling types?
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
a. Paracrine
b. Autocrine
c. Neurohormonal
d. Hormonal
ANS: A ilil
Paracrine signaling involves the release of local chemical mediators that are quickly taken up,
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
destroyed, or immobilized, as in the case of insulin and the inhibition of the secretion of
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
glucagon. None of the other options involve signaling that is associated with a local chemical
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
mediator like insulin.

ilil ilil ilil ilil ilil ilil ilil ilil ilil

ANS: B ilil
Each enzyme has a high affinity for a substrate, a specific substance converted to a product
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
of the reaction. Cellular metabolism is not dependent on an attraction between an enzyme
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
and any of the remaining options.

10. An athlete runs a marathon, after which his muscles feel fatigued and unable to contract.
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
The athlete asks the nurse why this happened. The nurse’s response is based on the
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
knowledgethat the problem is result of a deficiency of:
ilil il ilil ilil ilil ilil ilil ilil ilil ilil
a. GTP
b. AMP
c. ATP
d. GMP
ANS: C ilil
When ATP is deficient, impaired muscle contraction results. None of the other options are
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
involved in muscle contraction.

11. Which phase of catabolism produces the most ATP?
ilil ilil ilil ilil ilil ilil ilil
a. Digestion
b. Glycolysis
c. Oxidation
d. Citric acid cycle ilil ilil
ANS: D ilil
While some ATP is produced during the oxidation and glycolysis phases, most of the ATP is
ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil ilil
generated during the citric acid cycle. Digestion does not produce any ATP.
