Question

Which of the following factors are favourable for the formation of oxyhaemoglobin in alveoli?

विकल्प

• Low pCO₂ and High H⁺ concentration

• Low pCO₂ and High temperature

• High pO₂ and High pCO₂

• High pO₂ and Lesser H⁺ concentration

Answer 1

High pO₂ and Lesser H⁺ concentration

Explanation:

Compared to the tissues, which have low pO₂, high pCO₂, high H⁺ concentration, and higher temperatures, which are favourable for the dissociation of oxygen from the oxyhaemoglobin, the alveoli have high pO₂, low pCO₂, lower H⁺ concentration, and lower temperature, all of which are favourable for the formation of oxyhaemoglobin.
