Multiple Choice

1. Which Statement Best Describes The Cellular Function Of Metabolic Absorption?
A. Cells Can Produce Proteins.
B. Cells Can Secrete Digestive
Enzymes.
C. Cells Can Take In And Use
Nutrients.
D Cells Can Synthesize Fats.
.
ANS: C
In Metabolic Absorption, All Cells Take In And Use Nutrients And Other Substances From
Their Surroundings. The Remaining Options Are Not Inclusive In Their Descriptions Of
Cellular Metabolic Absorption.

2. Where Is Most Of A Cell’s Genetic Information, Including Rna And Dna, Contained?
A. Mitochondria
B. Ribosome
C. Nucleolus
D Lysosome
.
ANS: C
The Nucleus Contains The Nucleolus, A Small Dense Structure Composed Largely Of Rna,
Most Of The Cellular Dna, And The Dna-Binding Proteins, Such As The Histones, Which
Regulate Its Activity. The Mitochondria Are Responsible For Cellular Respiration And
Energy Production.
Ribosomes’ Chief Function Is To Provide Sites For Cellular Protein Synthesis. Lysosomes
Function As The Intracellular Digestive System.

3. Which Component Of The Cell Produces Hydrogen Peroxide (H2o2) By Using Oxygen To
Remove Hydrogen Atoms From Specific Substrates In An Oxidative Reaction?
A. Lysosomes
B. Peroxisomes
C. Ribosomes
D Endosome
.
ANS: B
Peroxisomes Are So Named Because They Usually Contain Enzymes That Use Oxygen To

, Remove Hydrogen Atoms From Specific Substrates In An Oxidative Reaction That Produces
H2o2, Which Is A Powerful Oxidant And Potentially Destructive If It Accumulates Or
Escapes From Peroxisomes. Ribosomes Are Rna-Protein Complexes (Nucleoproteins) That
Are Synthesized In The Nucleolus And Secreted Into The Cytoplasm Through Pores In The
Nuclear Envelope Called Nuclear Pore Complexes. Lysosomes Are Saclike Structures That
Originate From The Golgi Complex And Contain More Than 40 Digestive Enzymes Called
Hydrolases, Which Catalyze Bonds In Proteins, Lipids, Nucleic Acids, And Carbohydrates.
An Endosome Is A Vesical That Has Been Pinched Off From The Cellular Membrane.

4. Which Cell Component Is Capable Of Cellular Autodigestion When It Is Released
During Cell Injury?
A. Ribosome
B. Golgi Complex
C. Smooth Endoplasmic
Reticulum
D Lysosomes
.
ANS: D
The Lysosomal Membrane Acts As A Protective Shield Between The Powerful Digestive
Enzymes Within The Lysosome And The Cytoplasm, Preventing Their Leakage Into The
Cytoplasmic Matrix. Disruption Of The Membrane By Various Treatments Or Cellular
Injury Leads To A Release Of The Lysosomal Enzymes, Which Can Then React With Their
Specific Substrates, Causing Cellular Self- Digestion. The Chief Function Of A Ribosome Is
To Provide Sites For Cellular Protein Synthesis. The Golgi Complex Is A Network Of
Flattened, Smooth Vesicles And Membranes Often Located Near The Cell Nucleus. The
Smooth Endoplasmic Reticulum Is Involved In Steroid Hormone Production And Removing
Toxic Substances From The Cell.

5. Which Camp-Mediated Response Is Related To Antidiuretic Hormone?
A. Increased Heart Rate And Force Of
Contraction
B. Secretion Of Cortisol
C. Increased Retention Of Water
D Breakdown Of Fat
.
ANS: C
Antidiuretic Hormone Leads To Increased Retention Of Water In The Body. Epinephrine Causes
Increases In Heart Rate And Force Of Contraction. Increased Cortisol Secretion Is Due To Acth.
Breakdown Of Fat Is Due To Glucagon.

6. During Which Phase Of The Cell Cycle Is Dna Synthesized?
A. G1
B. S
C. G2
D M
.
ANS: B

, The Four Designated Phases Of The Cell Cycle Are: (1) The G1 Phase (G = Gap), Which Is
The Period Between The M Phase (M = Mitosis) And The Start Of Dna Synthesis; (2) The S
Phase (S
= Synthesis), During Which Dna Is Synthesized In The Cell Nucleus; (3) The G2 Phase,
During Which Rna And Protein Synthesis Occurs, The Period Between The Completion Of
Dna Synthesis And The Next Phase (M); And (4) The M Phase, Which Includes Nuclear
And Cytoplasmic Division.

7. What Organic Compound Facilitates Transportation Across Cell Membranes By
Acting As Receptors, Transport Channels For Electrolytes, And Enzymes To Drive
Active Pumps?
A. Lipids
B. Proteases
C. Proteins
D Carbohydrates
.
ANS: C
Proteins Have Several Functions, Including Acting As Receptors, Transport Channels For
Electrolytes, And Enzymes To Drive Active Pumps Lipids Help Act As The ―Glue‖ Holding
Cell Membranes Together. Proteases Cause The Breakdown Of Protein. Carbohydrates Are
Involved In Cellular Protection And Lubrication And Help Produce Energy Via Oxidative
Phosphorylation.

Dif: Cognitive Level: Remembering

8. Understanding The Various Steps Of Proteolytic Cascades May Be Useful In Designing
Drug Therapy For Which Human Diseases?
A. Cardiac And Vascular Disorders
B. Autoimmune And Malignant Disorders
C. Gastrointestinal And Renal Disorders
D Endocrine And Gastrointestinal
. Disorders
ANS: B
Understanding The Various Steps Involved In This Process Is Crucial For Designing Drug
Interventions. Dysregulation Of Proteases Features Prominently In Many Human Diseases,
Including Cancer, Autoimmunity, And Neurodegenerative Disorders. Cardiac, Vascular,
Gastrointestinal, Renal, And Endocrine Disorders Do Not Involve This Process.

9. Which Structure Prevents Water-Soluble Molecules From Entering Cells Across The
Plasma Membrane?
A. Carbohydrate Chains
B. Glycoprotein Channels
C. Membrane Channel Proteins
D Lipid Bilayer
