Multiple Choice
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 Single Circular
Chromosome A Nucleus
Free-Floating Nuclear
Material 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 Called A Prokaryote Contains Free-Floating Nuclear
Material But Has No Organelles.
Ref: P. 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?
Metabolic
Absorption
Communication
Secretion
Respiration
Ans: 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 Secretion Allows For The
Synthesizing Of New Substances.
Ref: P. 2
A Eukaryotic Cell Is Undergoing Dna Replication. In Which Region Of The
Cell Would Most Ofthe Genetic Information Be Contained?
Mitochondria
Ribosome
Nucleolus
Nucleus Cytoplasm
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, Which Is Located Withinthe Cell’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
Which Of The Following Can Remove Proteins Attached To The Cell’s
Bilayer By Dissolving Thelayer Itself?
Peripheral Membrane Proteins
Integral Membrane Proteins
Glycoproteins
Cell Adhesion Molecules
Ans: 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 Marks Cells And Does Not Float.
Ref: P. 7
Which Of The Following Can Bind To Plasma Membrane Receptors?
Oxygen
, Ribosomes
Amphipathic
Lipids Ligands
Ans: D
Ligands Are The Only Specific Molecules That Can Bind With Receptors On
The Cell Membrane.
Ref: P. 9
A Nurse Is Reviewing A Report From A Patient With Metastatic Cancer.
What Alternation In Theextracellular Matrix Would Support The Diagnosis
Of Metastatic Cancer?
Decreased Fibronectin
Increased Collagen
Decreased Elastin
Increased
Glycoproteins
Ans: A
Only A Reduced Amount Of Fibronectin Is Found In Some Types Of
Cancerous Cells, Allowing Them To Travel Or Metastasize.
Ref: P. 10
Which Form Of Cell Communication Is Used To Relate To Other Cells In
Direct Physical Contact?
Cell Junction
Gap Junction
Desmosome
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 Tight Junctions Are Associated With Cellular Communication.
