Rules
• 3 color cards= 3 Teams
• Team work + Individual Performance
• Highest scoring Team =Bonus marks to each team
member
• In a team, each member will have one number, and the
question can be asked to anyone ( Number will be
called out) if the student answers- team will get a plus
point and so does the student. If a student fails, it will
effect the students class performance!
• If the question is not answered by the team, it will be
passed on to the another team.
• Buzzer Round- questions to all team at a time, whoever
buzzes first, the marks will be bonus for that team
All The Best 

Proteins
1.How many different amino acids are used in
making proteins?
A. 12
B. 20
A. 32
2.Which parts of amino acids are involved in
peptide bonds?
A. The carboxyl group on one amino acid and
the side chain on the other
B. The carboxyl group on both amino acids
C. The amino group on one amino acid and
the carboxyl group on the other
D. The amino group on both amino acids
3. Which part of an amino acid gives it its unique
properties?
• A. The amino group
B. The carboxyl group
C. The side chain
4.In a folded protein, the nonpolar
(hydrophobic) amino acids tend to be:
• A. tucked away inside the protein.
B. exposed on the outside of the protein.
C. distributed randomly throughout the
protein.
5. What provides the information necessary to
specify the three-dimensional shape of a protein?
A. The protein's peptide bonds
B. The protein's interactions with other
polypeptides
C. The protein's amino acid sequence
D. The protein's interaction with molecular
chaperones
6. The biological activity of a protein is
determined by its:
A. peptide bonds.
B. amino acid sequence.
C. ability to form α helices.
D. ability to form β sheets.
7. A protein can be unfolded by a process
called:
A. renaturation.
B. denaturation.
C. oxidation.
D. reduction.
8.Which hydrogen bonds have been found to
stabilize a polypeptide's folded shape?
A. Hydrogen bonds between side chain atoms
B. Hydrogen bonds between backbone atoms
C. Hydrogen bonds between backbone atoms and
side chain atoms
D. All of the above
E. A and B, but not C
9.What does the term protein domain refer to?
Bonus question
• A. A region in the cell where a protein can be
found
B. A segment of a protein that can fold
independently into its own compact, threedimensional structure
C. The functional activity of a protein
D. The region on a protein that determines
how it folds into a three dimensional
structure.
10. Why are α helices and β sheets common
folding patterns in polypeptides?
• A. The unique amino acid sequences that generate
these folding patterns are common in polypeptides.
B. Molecular chaperones tend to fold polypeptides in
these common folding patterns.
C. Amino acid side chains are not involved in forming
the hydrogen bonds, allowing many different
sequences to adopt these folding patterns.
