Q188 / 200 · NEET 2024 · Zoology

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

  • Correct answer
    A
    High $\mathrm{pO}_2$ and Lesser $\mathrm{H}^{+}$concentration
  • B
    Low $\mathrm{pCO}_2$ and High $\mathrm{H}^{+}$concentration
  • C
    Low $\mathrm{pCO}_2$ and High temperature
  • D
    High $\mathrm{pO}_2$ and High $\mathrm{pCO}_2$

Solution

The correct answer is option (1) as Conditions favourable for formation of oxyhaemoglobin in alveoli are high $\mathrm{pO}_2$, less $\mathrm{H}^{+}$concentration low $\mathrm{pCO}_2$ and low temperature. Option (2), (3) and (4) are not correct as they do not favour the formation of oxyhaemoglobin.

Hence, the correct answer is option: 'A'.
