Question 10o The oxygen-hemoglobin dissociation curve demonstrates which of the following concepts? 0/1 point The lower the oxygen content of plasma (PO2) the more hemoglobin is saturated with oxygen allowing more efficient del up from alveoli air, CO2 is released from pulonary capllaries in equal amounts to due hemoglobins equal affinity for CO2 and 02 Because of hemoglobin's characteristic affinity for 02, an S shaped curve is exhibited when P02 of plasma is plotted saturation against percent h That oxygen is higher at the tissues du the tissues. e to the ability of hemoglobin to carry up to 10 molecules of oxygen which is then released and measured at Attempt Score:6 / 10-60 % Overall Grade (highest attempt):6 / 10 , 60 % /n/2 pe here to search

Explanation / Answer

Answer is c due to affinity of oxygen, s shaped curve is exhibited when po2 is plotted against haemoglobin % saturation.

explaination-the primary reason for the S shaped of oxygen-haemoglobin dissociation curve is that out of the four molecules of oxygen that can combine with haemoglobin molecules,the first combines with greatest difficulty and binding of an oxygen molecules increase affinity to next o2 molecule.this phenomenon is called as cooperative binding.
