Question

See the figure below. Which one of the following groups can become part of a peptide bond? a. A b. B c. C d. D e. E An acid is a molecule that releases a hydrogen ion (proton). a. True b. False Release of hydrogen ions to a solution would most likely a. raise pH b. lower pH c. buffer pH d. change salinity e. change osmolarity What type of protein secondary structure is characterized by its coiled structure? a. beta-pleated sheet b. double helix c. di-sulfide linkages d. integral protein e. alpha-helix Proteins are often composed of one or more distinct structural "modules" and they represent parts of a protein that may function in a semi-independent manner. These "modules" are called a. motifs b. lipid rafts c. ligands d. enzymes e. domains A group of atoms within in a molecule may lose or gain a proton when the molecule is placed in an aqueous solution. The exact probability that a molecule will be protonated or deprotonated depends on the pKa of the group of atoms and the pH of the solution. a. True b. False Consider the amino acid lysine within a protein: if you change the pH of the protein solution, the pKa for lysine will change too. a. True b. False
