Which of the following is NOT an indication that the binding of oxygen to hemoglobin is cooperative? a. Oxygen binding of one subunit induces a shift of the other hemoglobin subunits from the T state to the R state. b. A plot of hemoglobin’s fractional saturation against partial pressure of oxygen (Y versus pO2), is sigmoidal rather than hyperbolic. c.Hemoglobin has four subunits, each of which can bind oxygen. d.The Hill coefficient, n, is greater than 1.0.

5. Under normal physiological conditions, hemoglobin is half saturated with O2 at 26 torr, and the Hill coefficient nn = 2.8. What is the degree of saturation when the partial pressure of O2 in the tissue capillaries falls to 33 torr during gentle walking? A. 0.34 B. 0.41 C. 0.56 D. 0.66 E. 1.00

41. Which of the following statements about protein-ligand binding is correct? A) The K is equal to the concentration of ligand when all of the binding sites are occupied. B) The K is independent of such conditions as salt concentration and pH. C) The larger the K. (association constant), the weaker the affinity. D) The larger the K. the faster is the binding. E) The larger the K, the smaller the K. (dissociation constant) 42. The ability of O, to...

The density of methane gas is measured at four sets of conditions. Under which set of conditions is the density of CH4 the greatest? (a) T = 300K, P = 1 atm; (b) T = 325K, P = 1 atm; (c) T = 275K, P = 2 atm; (d) T = 300K, P = 2 atm
In a real hemoglobin molecule, the tendency of oxygen to bind to a heme site increases...
In a real hemoglobin molecule, the tendency of oxygen to bind to a heme site increases as the other three heme sites become occupied. To model this effect in a simple way, imagine that a hemoglobin molecule has just two sites, either or both of which can be occupied. This system has four possible states (with only oxygen present). Take the energy of the unoccupied state to be zero, the energies of the two singly occupied states to be -0.55...

6. Which of the following amino acid residues would provide a side chain capable of increasing the hydrophobicity of a binding site? A) aspartic acid B) lysine C) isoleucine D) arginine E) serine 7. Consider a hypothetical hemoglobin with a Hill coefficient of 1 and the same pso value as normal hemoglobin. Choose the statement below that best describes the two proteins. A) There is a cooperative interaction between oxygen-binding sites in both the hypothetical and normal hemoglobins. B) The...
