2) We discussed in class how the molecule 2,3-bisphosphoglycerate (BPG) is an inhibitor of hemoglobin (Hb). Answer the following questions about BPG and its regulation of oxygen binding: a) Would BPG have any effect on myoglobin’s ability to bind or release oxygen? If so, describe how BPG would affect myoglobin. If not, why? b) Based on the observation that BPG binds preferentially to partially deoxygenated Hb, briefly explain (1-2 sentences) where BPG is most likely to be most effective on...

Which of the following statements concerning the Bohr effect are true. Lowering the pH shifts the oxygen dissociation curve for hemoglobin to the right The acidic environment of an exercising muscle allows hemoglobin to bind O_2 more tightly The affinity of hemoglobin for O_2 is diminished by high concentrations of CO_2 In the lungs, the presence of higher concentrations of H^+ and CO_2 allows hemoglobin to become oxygenated In the lung, the presence of higher concentrations of O_2 promotes the...
