[ANIMAL PHYSIOLOGY] Which of the following statements about the oxygen-binding curves is FALSE? Select one: The PO2 and hemoglobin dissociation curve for myoglobin is to the left of fetal hemoglobin. O b. During high metabolic activity the PO2 and hemoglobin dissociation curve would be expected to shift to the left of normal. The blood returning to the lungs is still 75% saturated with oxygen. d. During normal activity (not exercising) the blood PO2 rarely falls below 40 mmHg. Oe. A larger decrease in PO2 is needed for hemoglobin to drop from 100% to 75% 02 capacity than from 75% to 50% 02 capacity.

Which of the following statements regarding control of respiration is TRUE? At high altitude, a decrease in PC02 of the blood stimulates an increase in ventilation. An increase in the HCO3- concentration in blood stimulates ventilation. A slight decrease in arterial PO2 is a stronger stimulus for increased ventilation than is a comparable decrease in arterial PCO2. The most important signal for regulating ventilation is the H+ concentration of arterial blood. Increased concentrations of lactic acid stimulate ventilation primarily by acting on peripheral chemoreceptors.
1. Is this statement correct or incorrect? Explain. During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right. This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 onto hemoglobin in the lungs. 2. Is this statement correct or incorrect? Explain. Compared to hemoglobin, myoglobin has a lower binding affinity for O2 and a higher O2 binding capacity, two characteristics that allow myoglobin to efficiently provide skeletal muscle cells with a readily-accessible reservoir of O2.
In Charles’ blood, the partial pressure of CO in the blood (0.4 mm Hg) is far lower than the partial pressure of O2, yet the percent saturation of hemoglobin by each gas is approximately equal. What does this tell you about the affinity of hemoglobin for CO?
