PROTEINS
A protein is:• A. Polymer• B. macromolecule• C. Biomolecule• D. Organic molecule• E. All of the above
The monomer of proteins:
• A. Monosaccharide• B. Fatty acid• C. Nucleic Acid• D. Amino acid• E. none of the above
Every protein:• A,. Has a unique 3-d shape that
corresponds to a specific function• B. Has similar shape• C. Has a different shape but not 3-D• D. . Has a unique 3-d shape unrelated
to function
Proteins are important to:
• A. Structure of cell• B. Carrying activities• C. Energy source• D. Insulation• E. Both A and B
All are major classes of proteins EXCEPT:
• A. structural G. Enzymes• B. defense H. Signal• C. Contractile• D. Transport• E. storage• F. Energy
Proteins are made by linking:
• A. Nucleic acids together• B. Amino acids together• C. Fatty acids together• D. Monosaccharides together
There are ____ amino acids
• A. 10• B. 15• C. 20• D. 25• E. 30
All amino acids have a central carbon
• A. true• B. False
All amino acids have a carboxyl group
• A. true• B. False
All amino acids have an amino group
• A. true• B. False
All amino acids have a hydrogen attached to central
carbon:• A. true• B. False
Every amino acid has a different R group attached to central
carbon• A. true• B. False
What determines properties of amino
acids?• A. Carboxyl group• B. Amino group• C. Central carbon• D. Hydrogen• E. R-group
Amino acids are linked together:
• A. By process of dehydration synthesis• B. By removal of water• C. By covalent bonds• D. By peptide bonds• E. All of the above
Chain of amino acids called:
• A. Monosaccharide• B. polysaccharide• C. Polypeptide• D. Triglyceride• E. Dipeptide
What determines a proteins function?
• A. Its shape• B. Zack• C. Sam• D. Bryan• E. B, C, and D are correct
Denaturation• A. The linking together of amino acids• B. The breaking apart of amino acids• C. The unfolding of a protein• D. The breaking apart of a
polysaccharide
Denaturation is caused by all
EXCEPT:• A. High temperature• B. low temperature• C. High pH• D. Low PH• E. Salt concentrations
Since all organisms use the same 20 amino
acids to make their proteins
• A. Evidence for Cell Theory• B. Evidence For Evolution• C. Evidence from common ancestry• D. Evidence of relatedness among
species• E. B, C, and D
