Frage 9
Frage
What is the difference between 'A' and 'B'?
Antworten
-
'A' would be found in a protein, but 'B' would not.
-
'A' is a sugar and 'B' is an amino acid.
-
'A' would be involved in secondary structure, and 'B' would be involved in tertiary structure.
-
'A' would be involved in different tertiary structure interactions than 'B'.

Antworten
-
Primary
-
Secondary
-
Tertiary
-
Quaternary
Frage 11
Frage
Why does a protein take on the shapes shown in this image?
Antworten
-
Because it contains amino acids
-
Because nonadjacent R groups interact with each other
-
Because the backbone of the protein is polar
-
Because it looks fabulous

Antworten
-
A protein
-
A steroid
-
A monosaccharide
-
Starch
Frage 16
Frage
The R group of the amino acid serine is highly polar. The R group of the amino acid leucine is highly nonpolar. Where would you expect to find these amino acids in a globular protein that is normally dissolved in water?
Antworten
-
Both serine and leucine would be in the interior of the protein.
-
Both serine and leucine would be on the exterior of the protein.
-
Leucine would be on the interior, and serine would be on the exterior of the protein.
-
Serine would be on the interior, and leucine would be on the exterior of the protein.
Frage 17
Frage
Which of the following is NOT a monomer?
Antworten
-
Amino acid
-
Monosaccharide
-
Steroid
-
All of these are monomers
Frage 18
Frage
Figure 1 illustrates a dipeptide, created through dehydration synthesis. At which bond would water need to be added to achieve hydrolysis of the peptide, back to its component amino acids?
Antworten
-
Bond A
-
Bond B
-
Bond C
-
Bond D
Frage 19
Frage
The functionality of a protein is determined by its shape when in its native conformation. The native conformation of a protein is determined by the set of amino acids that comprise the protein's sequence. A certain protein consists of 325 amino acids. What could be the result if one of the amino acids in this protein were changed?
Antworten
-
The primary structure of the protein would not be altered but its tertiary structure and function would be altered.
-
The tertiary structure would be changed but the protein's function would not be affected.
-
The primary structure, tertiary structure, and the biological function would be altered.
-
There would be no change to the structure or the function of the protein.
Frage 20
Frage
Which statement is true of the process shown in this image?
Antworten
-
A polymer is generated.
-
Hydrolysis is occurring.
-
A peptide bond is broken in the process.
-
More than one of these statements is true.
