NEET2024Biology

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

A
Low pCO $_{2}$ and High H $^{+}$ concentration
B
Low pCO $_{2}$ and High temperature
C
High pO $_{2}$ and High pCO $_{2}$
D
High pO $_{2}$ and Lesser H $^{+}$ concentration

Solution

Formation of oxyhaemoglobin is favoured by high pO $_{2}$ , low pCO $_{2}$ , low H $^{+}$ concentration (high pH) and lower temperature — conditions that exist in the alveoli. Hence high pO $_{2}$ together with low H $^{+}$ concentration is the correct combination.
