1.12 At elevated altitudes, the body adapts to the reduced barometric pressure to extract sufficient oxy- gen to permit normal metabolic functions and do work. For example, at an altitude of 3,650 m (close to 12,000 feet above sea level) the barometric pressure drops to 485 mmHg. For an oxygen pressure drop in the lungs of 30 mmHg, determine the oxygen uptake rate for a respiration rate of 20 breaths per minute. Estimate the oxygen saturation in venous blood if the hematocrit rises to 0.60 and the partial pressure of oxygen blood is at a partial pressure equal to 98% of the alveolar level.

Studies of oxygen transport in pregnant mammals show that the O2-saturation curves of fetal and maternal blood are markedly different when measured under the same conditions. Fetal erythrocytes contain astructural variant of hemoglobin, HbF, consisting of two α and two γ subunits (α2 γ2 ), whereas maternal erythrocytes contain HbA (α2β2).(a) Which hemoglobin has a higher affinity for oxygen under physiological conditions, HbA or HbF? Explain.(b) What is the physiological significance of the different O2 affinities?(c) When all the BPG is carefully removed from samples of HbA and HbF, the measured O2 -saturation curves (and consequently the O2 affinities) are displaced to the left. However, HbA now has a greater affinity for oxygen than does HbF. When BPG is reintroduced, the O2 -saturation curves return to normal, as shown in the graph. What is the effect of BPG on the O2 affinity of hemoglobin? How can the above information be used to explain the different O2 affinities of fetal and…

Under appropriate conditions, hemoglobin dissociates into its four subunits. The isolated α subunit binds oxygen, but the O2 -saturation curve ishyperbolic rather than sigmoid. In addition, the binding of oxygen to the isolated α subunit is not affected by the presence of H+, CO2 , or BPG. What do these observations indicate about the source of the cooperativity in hemoglobin?
