Changes in hemoglobin's oxygen affinity are primarily the result of changes in the structure of the protein. A. tertiary D.secondary a. 3. In sickle cell hemoglobin, a Glu is mutated to a b. B. quaternary C. C. primary 4. In a mixture of the five proteins listed below, which should elute out second in a size- exclusion (gel- filtration) chromatography? A. immunoglobulin G C. cytochrome c Mr = 145,000 M,= 13,000 E. ribonuclease A M₁ = 13,700 d. e. E. all of the above This causes the formation of between hemoglobin molecules, ultimately forming large aggregates. 5. The Pl of amino acids lysine and glycine are 9.2 and 6.0. If the two amino acids are dissolved and subjected to electrophoresis in a buffer solution of pH = 7, Then Both will moved to the negative end Both will moved to the positive end Both will not move lysine moves to negative end while glycine moves to positive end lysine moves to positive end while glycine moves to negative end C. Arg; salt bridges B. Val; hydrophobic interactions A. Cys; disulfide bonds D. Pro; disrupted a-helix, resulting in several H-bonds and salt bridges B. serum albumin D.
