(1) A lower numerical value of oxygen (O2) P50 indicates a higher hemoglobin affinity for O2. Note: O2 P50 is the oxygen partial pressure (PO2) at which 50% of hemoglobin molecules are saturated with O2.
(2) A lower numerical value of oxygen (O2) P50 indicates a lower hemoglobin affinity for O2. Note: O2 P50 is the oxygen partial pressure (PO2) at which 50% of hemoglobin molecules are saturated with O2.
(3) The O2 P50 value of fetal hemoglobin is smaller (in numerical value) than the O2 P50 value of meternal hemoglobin. Note: O2 P50 is the oxygen partial pressure (PO2) at which 50% of hemoglobin molecules are saturated with O2.
(4) Fetal hemoglobin has a lower affinity for oxygen (O2) than maternal hemoglobin.
(5) Which of the following decrease(s) the affinity of hemoglobin for oxygen (O2)?
