Test Bank for Huether and McCances Understanding Pathophysiology

2nd CANADIAN Edition Power Kean Chapter 1 - 42


Chapter 01: Cellular Biology




MULTIPLE CHOICE




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




ANSWERS: 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.

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




ANSWERS: 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




ANSWERS: 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

ANSWERS: 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




ANSWERS: 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.
