La cut A. T Normal T No Spac.. Heading Paragrap QUESTION 5 The secondary structure of a protein is stabilized by which type of bond? C A.covalent peptide bond C B.hydrogen bond C C disulfide bond c D.ionic bond 1· QUESTION 6 A hydrophobic amino acid R group (side group) would be found where in a protein? 1. A. forming a peptide bond with the next amino acid in the polypeptide chain B. on the outside of the folded chain, in the water C c on the inside of the folded chain, away from water D.forming hydrogen bonds with other R groups r E. only at one end of a protein chain QUESTION 7 What color was the solution with the lowest concentration of protein? C A purple 1. B. red D. brown QUESTION 8 1. When draving a standard curve, what goes on the x-axis? A concentration B. time C absorbance D. transmittance

Explanation / Answer

ANSWER:

5) B.Hydrogen Bond

The secondary structure of a protein is stabilized by Hydrogen bond

The secondary structure describes the three-dimensional folding or coiling of a chain of amino acids (e.g., beta-pleated sheet, alpha helix).

6) C. On the inside of the folded chain,away from water

A hydrophobic amino acid R group would be found in  On the inside of the folded chain,away from water

7) C.Blue

Blue color was the solution with the lowest concentration of protein.The proteins in the gel are preferentially stained by the low concentration of free dye, but the matrix remains unstained because the colloidal dye particles are excluded from the gel.

8) A.Concentration

Data for known concentrations of protein are used to make the standard curve, plotting concentration on the X axis,
