CORRECT|GRADE A+
What is meant by native configuration?
A. The secondary structure of protein
B. The tertiary structure of protein in its folded state with lowest entropy
C. Linear polymer of amino acids
D. The sequence amino acids coded by the gene - ANSWER B. The tertiary structure of protein in its
folded state with lowest entropy
What bond holds amino acids in a linear hetropolymer?
A. Glyocsidic bond
B. Ester linkage
C. Peptide bond
D. Phosphodiester bond - ANSWER C. Peptide bond
Digestion of a protein is a process called?
A. Dehydration synthesis
B. Hydrolysis
C. Esterification
D. Proteolysis - ANSWER B. Hydrolysis
Which of the following pair of amino acids is expected to be found on the interior of a globular protein?
A. Lys and Arg
B. Arg and Leu
C. Val and Asp
D. Trp and Phe - ANSWER D. Trp and Phe
, It wouldn't have polar ones on the inside, Arg is polar, so none with Arg as a choice are right, and Asp is
polar too because it is an acid, so that one can't be a choice either
What is meant by calling the peptide bond a resonance structure?
A. The bond between the atoms vibrates
B. The bond between the atoms form a partial double bond
C. The bond is cis
D. All of the above - ANSWER B. The bond between the atoms form a partial double bond
The peptide bond is formed between which two groups of the amino acids?
A. The amine group of the first amino acid to the carbonyl of the second amino acid in a polypeptide
B. Between the R group of the first and the R group of the second amino acid in a polypeptide
C. The alpha carbons of each amino acid in a polypeptide
D. The carboxylic acid group of the first and the amine of the second amino acid in a polypeptide -
ANSWER D. The carboxylic acid group of the first and the amine of the second amino acid in a
polypeptide
What is the spatial orientation of amino acids in a peptide?
A. Amino acids are trans of each other
B. Each amino acid is cis of its neighbor
C. Can be either cis or trans
D. None of the above - ANSWER A. Amino acids are trans of each other
The reason why there is a small dipole charge along a peptide is because
A. The charge of the R groups
B. The charge on the alpha carbon
C. The charge of the amine nitrogen and the carbonyl group
D. None of the above - ANSWER C. The charge of the amine nitrogen and the carbonyl group
