[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.
