Chapter 01: Cellular Biology
MULTIPLE CHOICE
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 bythe student?
a. A single circular chromosome
b. A nucleus
ANS: B
c. Free-floating nuclear material
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNAwithin its nucleus;
d. the nucleus
thus, No organelles
should be observed.
A single circular chromosome is characteristic of prokaryotic cells, which do not havehistones.
Free-floating nuclear material describes a prokaryotic cell, which would not have adistinct nucleus.
Eukaryotic cells have membrane bounded cellular components called organelles. Noorganelles describes a
prokaryotic cell.
REF: p. 2
2. A nurse is instructing the staff about cellular functions. Which cellular function isthe nurse describing
when an isolated cell absorbs oxygen and uses it to transform nutrients to energy?
a. Metabolic absorption
b. Communication
c. Secretion
d. D
ANS: Respiration
The ability of the cell to absorb oxygen refers to the cell’s function of respiration.
The ability of the cell to function within a society of cells refers to its function ofcommunication.
The ability of the cell to take in nutrients refers to the cell’s function of metabolicabsorption.
The ability of the cell to synthesize new substances and secrete these elsewhere refersto the cell’s function of
secretion.
REF: p. 3
3. A eukaryotic cell is undergoing DNA replication. In which region of the cell wouldmost of the genetic
information be contained?
2 | Pa.a g e Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus
, 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. The mitochondria is the site of cellular
respiration.
The ribosomes are involved in manufacturing of proteins within the cell.
The nucleus contains the nucleolus, and it is the nucleolus that contains geneticmaterial.
REF: p. 5
4. The fluid mosaic model for biologic membranes describes membrane behavior. According to this
model, which of the following float singly or as aggregates in thefluid lipid bilayer?
a. Peripheral membrane proteins
b. Integral membrane proteins
c. Glycoproteins
d. B
ANS: Cell adhesion molecules
Integral membrane proteins float freely in the fluid lipid bilayer.
Peripheral membrane proteins are not embedded in the layer, but reside at the surface.Glycoproteins act as
cell surface markers.
Cell adhesion molecules are on the outside of the membrane and allow cells to hooktogether.
REF: p. 6
5. Which of the following can bind to plasma membrane receptors?
a. Oxygen
b. Ribosomes
c. Amphipathic lipids
d. Ligands
ANS: D
Ligands are specific molecules that can bind with receptors on the cell membrane.Oxygen moves by
diffusion; it does not bind to receptors.
Ribosomes make proteins and are not involved in binding.Amphipathic
lipids are a portion of the cell membrane.
REF: p. 11
6. A nurse is reviewing a report from a patient with metastatic cancer. What finding would support the
diagnosis of metastatic cancer? Alterations in extracellular matrixthat include:
3 | Pa.a g e Decreased fibronectin
b. Increased collagen
c. Decreased elastin
, ANS: A
Reduced amounts of fibronectin are found in some types of cancerous cells, allowingcancer cells to travel,
or metastasize.
Collagen provides strength, and its breakdown is associated with osteoarthritis, notcancer.
Elastin is found in the lungs and allows tissues to stretch; it is not associated withcancerous cells.
Decreased, not increased, glycoproteins are associated with cancerous cells.REF: p. 8
7. Which form of cell communication is used to relate to other cells in direct physicalcontact?
