1.
On the bottom of p.80 your text states that, "a protein is not just a polypeptide chain". So what is a protein? Answers will NOT be counted correct unless they are in your own words - look on p.80 for this specific spot for the best answer.
2.
Explain what Fig. 5.19 is showing IN YOUR OWN WORDS.
3.
List 4 things that can cause a protein to become denatured.
4.
What happens if proteins are created with an incorrect shape?
5.
What is the name of the process that joins monomers together to make polymers?
A. 
B. 
C. 
D. 
E. 
6.
In hydrolysis, __________________ , and in this process water is _________________________ .
A. 
A polymer breaks up to form monomers ... consumed
B. 
A monomer breaks up to form polymers ... produced
C. 
Monomers are assembled to produce a polymer ... consumed
D. 
Monomers are assembled to produce a polymer ... produced
E. 
A polymer breaks up to form monomers ... produced
7.
In science knowing Latin and Greek roots is frequently helpful in understanding definitions. One example is hydrolysis because hydro- refers to water and -lysis means __________________ which is literally what happens during the process of hydrolysis.
8.
Figure 5.15 in your textbook shows 8 of the possible functions of proteins in living things. In each of the 8 smaller pictures (except structural proteins), the proteins are shown in the color _________________________.
9.
Check any of the following that are possible functions of proteins. Consult Fig. 5.15 in your text for help.
A. 
Transporting substances in/out of cells.
B. 
As a support protein in hair, feathers, connective tissues, etc.
C. 
As hormones that cause other tissues to respond.
D. 
As amino acids that make polypeptides.
E. 
As enzymes that speed up chemical reactions.
10.
The major parts of an amino acid are a central Carbon atom, an amino group, a carboxyl group, a single Hydrogen atom, and an R group which is identical in all 20 amino acids.
11.
According to Fig. 5.16 in your textbook, amino acids can be divided into 3 major categories based on their properties. These categories are _______________, polar, and electrically charged.
12.
Using Fig. 5.16 in your textbook you can see that molecules that are polar are also considered ______________________, or water loving.
13.
Every time a peptide bond is created to link 2 amino acids together a ______________ molecule is released. (See Fig. 5.17 for help)
14.
In Fig. 5.17 in your textbook, how many amino acids are shown linked together in the molecule in the lower half of the diagram?
A. 
B. 
C. 
D. 
E. 
F. 
15.
Every protein (polypeptide) has a free ________________ on one end and a free ___________________ on the other end.
A. 
Carboxyl group......R group
B. 
Amino group.....carboxyl group
C. 
C-terminus........C-terminus
D. 
A-terminus.......A-terminus
16.
A polypeptide is the same as a protein.
17.
What determines the 3-D structure that a protein will have?
A. 
Globular protein associations with amino acids
B. 
Fibrous protein associations with amino acids
C. 
The amino acid sequence of the protein
D. 
Whether the protein contains electrically charged amino acids
18.
Fig. 5.18(a) shows the way that 1 polypeptide chain folds in 3-D space, but it also shows something else in yellow that helps the polypeptide keep its correct conformation. These yellow lines are:
A. 
B. 
C. 
D. 
19.
Which level of protein structure would describe a protein or polypeptide as having a-helices or b-pleated sheets?
A. 
B. 
C. 
D. 
20.
Which level of protein structure would tell you whether a protein is made of more than one polypeptide chain?
A. 
B. 
C. 
D. 
21.
Which level of protein structure takes into account the total 3-D shape of a protein/polypeptide including its hydrophobic interactions which organize all hydrophobic R-group amino acids into the shielded center of the protein/polypeptide.
A. 
B. 
C. 
D. 
22.
Which level of protein structure takes into account only the protein's simple sequence of amino acids?
A. 
B. 
C. 
D. 
23.
How many amino acid changes are required to truly alter the function of a protein? (See the sickle-cell example on p.84)
A. 
B. 
C. 
D. 
24.
If a protein is denatured by heat or chemicals it can actually recover and go back to its functional shape once the heat or chemicals are removed.
25.
Special proteins that help newly made polypeptides to fold into their 3-D shapes correctly are called ____________________.
