Why is it advantage that fetal hemoglobin has a higher affinity for oxygen than maternal hemoglobin?

adult Hb ha 2-alpha+2delta structure while fetal has 2-alpha+2-gamma.
and this renders it more interactive towards oxygen, hence fetal hb has more affinity for oxygen as compared to adult hemoglobin.

Why is fetal hemoglobin unsuitable to use after birth?
Fetal haemoglobin has a higher affinity for oxygen, so is less able to dissociate than maternal haemoglobin within body tissues and cells.
Does a low pH decrease hemoglobins affinity for oxygen?
Yes. This an example of the Bohr effect. If pH is lower than normal (normal is 7.4), then hemoglobin does not bind oxygen as well. The higher the pH, the lower the H ion concentration, the lower the carbon dioxide level, and the GREATER affinity hemoglobin has for oxygen. The binding of oxygen to hemoglobin in the lungs is not affected by changing the pH.
How does carbon monoxide impair the delivery of oxygen to tissue?
CO binds hemoglobin with a higher affinity than Oxygen. so hemoglobin bound to CO in the pulmonary capillaries will not become oxygenated. CO poisoning leads to hypoxia.
Which has higher electron affinity Iodine or bromine?
Bromine has a higher electron affinity.
In humans the embryonic and fetal forms of hemoglobin have a higher affinity for oxygen than that of adults This is due to?
nonidentical genes that produce different versions of globins during development.
How does inhaling carbon decrease the oxygen level in your blood?
Carbon monoxide, which has a higher affinity for hemoglobin in the red blood cell, displaces oxygen from the hemoglobin molecule, thus decreasing the oxygen level in the bloodstream, and reducing its delivery to the bodily tissues and cells.
Which has higher electron affinity fluorine or chlorine?
Fluorine has higher electron affinity than any other element.
Which has a higher affinity for glucose: hexokinase or glucokinase?
Hexokinase
How do high-altitude locations affect breathing rate?
The amount of oxygen is same. The partial pressure of oxygen is lower at higher altitude. The reason why lungs must work harder is because oxygen is required in the body to supply hemoglobins in the blood. The affinity of hemoglobin to oxygen becomes lower as the partial pressure of oxygen decreases, creating a higher breathing rate in order to acquire more oxygen. Take an example of llama that lives up high in mountains. Their body is well adapted to it, such that their hemoglobin's affinity to oxygen is much higher than that of humans, and does not require extra work in order to acquire more oxygen.
Do Nonmetals with lower electron affinity have higher reactivity?
No. The most reactive non metal, fluorine, has the highest electron affinity.
Who has higher electron affinity between bromine and Iodine?
According to Zumdahl, Group 7A elements (halogens) follow the expected behavior or periodicity as you follow top to bottom. The numbers (top to bottom) are getting closer to 0, so they are decreasing in electron affinity. Bromine has a higher negative # therefore it is a higher electron affinity.---papajohn
Why does the oxidation of organic compounds by molecular oxygen to produce CO2 and water release free energy?
the covalent bonds in organic molecules are higher energy bonds than those in water and carbon dioxide.
