Because nonadjacent R groups interact with each other
Because the backbone of the protein is polar
Because it looks fabulous
Which statement best explains why proteins can serve so many different functions?
They are soluble in water.
They vary in terms of chain length (i.e., the number of amino acids present).
They contain sulfur.
They have different shapes.
A mystery molecule contains nitrogen. What is the molecule most likely to be?
A mystery molecule is added to a test tube of water, and it floats to the top. What is the molecule most likely to be?
A mystery molecule quickly dissolves in water. It has a relatively low molecular weight (as compared to other biological molecules). What is the molecule most likely to be?
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?
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.
Which of the following is NOT a monomer?
All of these are monomers
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?
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?
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.
Which statement is true of the process shown in this image?
