Chapter 1. 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 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 is characteristic of
prokaryotic cells, which do not have histones. Free-floating nuclear material describes a
prokaryotic cell, which would not have a distinct nucleus. Eukaryotic cells have membrane-
bound cellular components called organelles. No organelles describe a prokaryotic cell.
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 ability of the cell to absorb oxygen refers to the cells function of respiration. The ability of
the cell to function within a society of cells refers to its function of communication. The ability
of the cell to take in nutrients refers to the cells function of metabolic absorption.The ability of
the cell to synthesize new substances and secrete these elsewhere refers to the cells function of
secretion.

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
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 the manufacturing of proteins within the
cell. The nucleus contains the nucleolus, and it is the nucleolus that contains genetic material.
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 the fluid
lipid bilayer?
a. Peripheral membrane proteins
b. Integral membrane proteins
c. Glycoproteins
d. Cell adhesion molecules
ANS: B
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 hook
together.

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.
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 matrix that
include:
a. Decreased fibronectin
b. Increased collagen
c. Decreased elastin
d. Increased glycoproteins
ANS: A
Reduced amounts of fibronectin are found in some types of cancerous cells, allowing cancer
cells to travel, or metastasize. Collagen provides strength, and its breakdown is associated with
osteoarthritis, not cancer. Elastin is found in the lungs and allows tissues to stretch; it is not
associated with cancerous cells. Decreased, not increased, glycoproteins are associated with
cancerous cells.

7. Which form of cell communication is used to relate to other cells in direct physical
contact?
a. Cell junction
b. Gap junction
c. Desmosomes
d. Tight junctions
ANS: A
Cell junctions hold cells together and permit molecules to pass from cell to cell. Gap junctions
allow communication from the inside of one cell to the inside of another. Desmosomes are not
involved in communication, but allow cells to hold together. Tight junctions are barriers that
prevent movement of some substances and leakages of others.
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
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. When cells produce signals that they themselves respond to, autocrine signaling is
used. Neurohormonal signaling involves secretion of hormones into the bloodstream by
neurosecretory hormones. Hormonal signaling involves specialized endocrine cells that secrete
hormone chemicals released by one set of cells that travel through the tissue through the
bloodstream to produce a response in other sets of cells.
