Actually bpg lowers the affinity of hemoglobin for binding to oxygen . It helps unloading the oxygen content near the tissues that need it like muscles . Hope I helped !
Yes, a low pH (acidic environment) decreases hemoglobin's affinity for oxygen. This is known as the Bohr effect, where pH and carbon dioxide levels affect oxygen-hemoglobin binding. In an acidic environment, hemoglobin releases oxygen more readily to tissues where it is needed.
The primary factor that determines how much oxygen is actually bound to hemoglobin is the partial pressure of oxygen (pO2) in the hemoglobin solution.
As it shifts to the right, it means that haemoglobin has a lesser affinity for oxygen
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.
The highest oxygen affinity is demonstrated by fetal hemoglobin (HbF), due to its higher affinity for oxygen compared to adult hemoglobin (HbA). This allows for efficient oxygen transfer from the mother to the fetus in the placenta.
Oxygen.
Factors that affect the release of oxygen to tissues include the level of oxygen in the blood, the pH level of the blood, temperature, carbon dioxide levels, and the affinity of hemoglobin for oxygen. These factors can influence how readily oxygen is released from hemoglobin into body tissues where it is needed for cellular respiration.
Sodium, when exposed to air has a great affinity for oxygen, such that it bursts into flame
Hemoglobins are proteins found in red blood cells that help carry oxygen from the lungs to the rest of the body and transport carbon dioxide back to the lungs to be exhaled. They are essential for maintaining healthy oxygen levels in the body.
Loading/uptake/association of oxygen at high p.O 2; In lungs (haemoglobin) is (almost) fully saturated / in lungs haemoglobin has a high affinity for oxygen; Unloads/releases/dissociates oxygen at low p.O 2; Unloading linked to higher carbon dioxide concentration;
It effects the digestive system because oxygen releases energy from glucose
