WGU C785 ACTUAL EXAM QUESTIONS
AND DETAILED CORRECT ANSWERS
Alteration of Protein Structure through Denaturation - correct
answer- Protein shape can be altered by breaking the bonds
that hold it together
Form=function, you break the form you break the function.
Denaturation of bonds
Disulfide bond: Strong reducing agent
Ionic, hydrogen bond: pH change
Ionic, hydrogen bond: High salt concentration
Hydrophobic interaction: Heat (fever)
Amino acid - correct answer- Building blocks of proteins.
Amino group + Carboxylic acid + R group = Amino acid
Nitrogen with at least
one Hydrogen attached
Can be NH2 or NH3+
Carbon that sits
, between amino
and carboxyl.
Hydrogen "hat"
Carbon with two
attached oxygens
Can be COOH or COO-
Amino Acid Structure - correct answer- Consist of a
Backbone side chain/R group
Carboxyl group: Carbon with two attached oxygens
Can be COOH or COO-
Amino Group: Nitrogen with at least one Hydrogen attached Can
be NH2 or NH3+
Alfa Carbon (a carbon): Carbon that sits between amino
and carboxyl Hydrogen "hat"
Side chain/R group: consists of...
Varible group: Unique portion of the
amino acid.
