What is the role of hemoglobin in the body Brainly?
Answer: Hemoglobin is the oxygen transporting protein of red blood cells.It carry oxygen and transport it throughout the body via blood circulation.
Why does fetal hemoglobin have a different binding curve?
Hemoglobin F has a different composition from the adult forms of hemoglobin, which allows it to bind (or attach to) oxygen more strongly. This way, the developing fetus is able to retrieve oxygen from the mother’s bloodstream, which occurs through the placenta found in the mother’s uterus.
Which does not affect Oxyhaemoglobin curve?
High O2 and high haemoglobin.
What causes a shift to the right in the oxyhemoglobin dissociation curve?
Factors which result in shifting of the oxygen-dissociation curve to the right include increased concentration of pCO2, acidosis, raised temperature and high concentrations of 2,3 diphosphoglycerate (2,3 DPG). These factors, in effect, cause the Hb to give up oxygen more readily.
What are the 4 factors that can cause a right shift to the Oxyhaemoglobin saturation curve?
Right shift
- low blood pH (lactic acid)
- high temperature – especially working muscles.
- high partial pressure of carbon dioxide (PCO2)
- increased 2,3-bisphosphoglycerate (2,3-DPG) – an intermediate of glycolysis.
What is the oxyhemoglobin dissociation curve and why is it important?
The oxyhemoglobin dissociation curve (OHDC) indicates the relationship between the oxygen saturation of hemoglobin (Sao2) and the partial pressure of arterial oxygen (Pao2). Neither linear nor static, the curve can change or shift depending on various factors.
Why is hemoglobin curve sigmoidal?
Hemoglobin’s oxygen-binding curve forms in the shape of a sigmoidal curve. This is due to the cooperativity of the hemoglobin. Both these changes causes the hemoglobin to lose its affinity for oxygen, therefore making it drop the oxygen into the tissues.
