2. Which of the following statements about aromatic amino acids is correct? (A) All are strongly hydrophilic. (B) Histidine is categorized as aromatic. (C) On a molar basis, tryptophan absorbs more ultraviolet light (280 nm) than tyrosine. (D) The major contribution to the characteristic absorption of light at 280 nm by proteins is the phenylalanine R group. (E) The presence of a ring structure in an amino acid determines whether or not it is aromatic.

4. The six atoms of the peptide group lie in a single plane as depicted in the picture below. In the picture, "R" represent the side chains, and a few atoms are labeled. Which side is closer to the C-terminus of this short peptide. (A) Right side (B) Left side (C) Both sides possible (D) Can't tell from limited information (E) Neither side

(B) Comparing proteins 1 and 2 reveals that these two proteins have diverged the most throughout evolution. (C) Protein 4 is the protein that shows the greatest overall homology to protein 1. (D) Proteins 1 and 4 show a greater evolutionary distance than proteins 1 and 2. (E) The portions of amino acid sequence shown suggest that these proteins are completely unrelated.

7. Which of the following statements about the folding of polypeptides is false? (A) Burial of hydrophobic amino acid R groups to exclude water (B) Alpha helices and beta sheet generally are usually found in different structural layers. (C) Polypeptide segment adjacent to each other in the primary sequence are always far away to each other in the folded structure. (D) Connections between elements of secondary structure do not form knots in most times. (E) Left handed connection between beta strands is very rare.

8. Two heme-binding proteins (myoglobin and hemoglobin), A and B, can bind oxygen. Which of the following statement is correct?. (6, fraction) (A) The plot below describes the behavior of A when it binds oxygen under different pH (B) The plot below describes the behavior of B when it binds oxygen under different pH (C) The plot below describes the behavior of both A and B when they bind oxygen under different pH (D) The curves can't describes the behavior of A or B (E) Hemoglobin does not bind oxygen at pH 7.4

(B) at equilibrium, the concentration of C will be less than the concentration of A. (C) at equilibrium, the concentration of C will be much greater than the concentration of A or B. (D) C will rapidly break down to A + B. (E) when A and B are mixed, the reaction will proceed rapidly toward formation of C.
