During aerobic activity, we depend on hemoglobin to pick up oxygen in the lungs and deliver it to tissues in a cooperative manner. Which of the traces on the graph shown accurately shows cooperative binding/release of oxygen from hemoglobin? 1.0 0.8 B 0.6 Y (fractional saturation) 0.4 0.2 0.0 0 50 200 100 150 pO2 (torr) Figure OA OB С

How does BPG, or 2,3-biphophoglycerate produce the shift in
the oxygen bunding curves shown? (BPG works to effect the binding
of oxygen to hemoglobin) Circle the correct choice.
a) BPG binds to the R state of hemoglobin tetramer.
b) BPG binds to the T state of hemoglobin tetramer.
c) BPG binds to the heme group, which blocks access to the
oxygen
d) BPG oxidizes the iron (II) in the heme group to the iron
(III), preventing oxygen from binding.

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.

Which of the following statement(s) is/are TRUE regarding the binding of oxygen to hemoglobin? A. The pH difference between the lungs and the surrounding tissues that decreases efficiency in oxygen transport is known as the Bohr effect. B. 100% of CO2 is transported by formation of a carbamate bond with the amino terminal residues in the hemoglobin chains. C. 2,3-Bisphosphoglycerate stabilizes the T state. D. All of the statements are true.
