MULTIPLE CHOICES
1. A Student Is Observing A Cell Under The Microscope. It Is Observed To Have
Supercoiled DNA Wi Th 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 Nu Cleus; Thus, The Nucleus Should Be Observed. A Single Circular
Chromosome Called A Pro Kary Ote Contains 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 De Scribing When An Isolated Cell Absorbs Oxygen And Uses It To Transform
Nutrients To Energ Y?
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
Edition
Communication Ability In Volves Maintenance Of A Steady Dynamic State, Metabolic
Absorption Provides Nutrition, And Secr Etion Allows 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 Th E Genetic 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
Ribonucleica C Id, Most Of The DNA, And DNA-
Binding Proteins, Is The Nucleolus, Which Is Located Withinthe Cell’s Nucleus.
Mitochondria Is A Ssociated With Cellular Respiration, While Ribosomes Are Involved
With Protein Manufactur Ing. Cytoplasm is A Fluid Filling That Is A Component Of The
p
Cell.
REF: P. 2
4. Which Of The Following Can Remove Proteins Attached To The Cell’s Bilayer By
Dissolving The La Yer 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 Me Mbrane Proteins That Dissolve The Bilayer. Peripheral Membrane Proteins
Reside At The Su Rface While Cell Adhesion Molecules Are On The Outside Of The
Membrane. Glycoprotein Mark S Cells A Nd Does Not Float.

a. Oxygen Edition
b. Ribosomes
c. Amphipathic Lipids
d. Ligands
ANS: D
Ligands Are The Only Specific Molecules That Can Bind With Receptors On the Cell Membrane.p

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 Th Em To Travel Or Metastasize.
REF: P. 10
7. Which Form Of Cell Communication Is Used To Relate To Other Cells In Direct Physical Contact?
a. Cell Junction
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
Tightju Nct Ions Are Associated With Cellular Communication.
