Which Level Of Protein Structure Is Disrupted Through The
Hydrolysis Of Peptide Bonds?
Quaternary
Tertiary
Primary
Secondary - ANS-Primary
The Primary Structure Of A Protein Is The Sequence Of Amino Acids
Held Together By Peptide Bonds. Peptide Bonds Are Formed By
Dehydration Reactions And Disrupted By Hydrolysis.
A Mutation In The Beta-Hemoglobin Gene, Which Results In The
Replacement Of The Amino Acid Glutamate In Position 6 With The
Amino Acid Valine, Leads To The Development Of Sickle Cell
Anemia. The Structures Of Glutamate And Valine Are Shown Below.
If The Beta Hemoglobin Gene In A Patient With Sickle-Cell Anemia
Were To Be Edited So That The Valine In Position 6 Was Replaced
With A Different Amino Acid, Which Replacement For Valine Would
Be Expected To Have The Best Clinical Outcome, In Theory, For The

Patient? (Assume The Valine Can Potentially Be Replaced With Any
Amino Acid Other Than Glutamate.) - ANS-The Original Amino Acid
In A Healthy Patient Is Glutamate, Which Is Negatively Charged. The
Mutated Amino Acid Is Valine, Which Is Non-Polar. Valine Is
Causing Sickle Cell Anemia. The Best Amino Acid To Replace Valine
So That The Patient Is Healthy Again Would Be The One Most Like
Glutamate, So Any Negatively Charged Amino Acid.
Secondary, Tertiary, And Quaternary Levels Of Protein Structure Can
All Be Impacted By Exposing A Protein To Which Treatment?
Change Of A Hydrophobic Amino Acid To A Different Hydrophobic
Amino Acid
Addition Of A Reducing Agent
Placement Of The Protein In A Solution With A Low Ph
Increase In The Concentration Of The Protein In Solution - ANS-
Placement Of The Protein In A Solution With A Low Ph
Changes In Ph Affect Hydrogen Bonds And Ionic Bonds. Hydrogen
Bonds In The Backbone Of Amino Acids Occur In Secondary
Structure, And Both Hydrogen Bonds And Ionic Bonds Occur In The
Side Chains Of Amino Acids In Tertiary Structure.

An Increase In Beta-Pleated Sheet Structure In Some Brain Proteins
Can Lead To An Increase In Amyloid Deposit Formation,
Characteristic Of Some Neurodegenerative Diseases. What Is The
Primary Biochemical Process That Follows The Increase In Beta-
Pleated Sheet Structure That Leads To The Development Of The
Amyloid Deposits?
An Increase In Glycogen Formation In The Brain Cells
Aggregation Of The Proteins In The Brain
Secretion Of Glucagon, Leading To Excessive Ketogenesis
An Increase In Anaerobic Metabolism Of Glucose In The Brain -
ANS-Aggregation Of The Proteins In The Brain
This Question Is Describing Changes In Protein Structure.
Aggregation Occurs When Proteins Clump Together Inappropriately,
Causing Plaques Like Amyloid Deposits To Accumulate.
Which Level Of Protein Structure Is Determined By The Sequence Of
Amino Acids?
