Question

Which of the following condition favours the dissociation of oxyhaemoglobin into oxygen and deoxyhaemoglobin?

पर्याय

• Low O₂ pressure in tissue.

• High O₂ pressure in tissue.

• Equal O₂ pressure inside and outside tissue.

• All times irrespective of O₂ pressure.

Answer 1

Low O₂ pressure in tissue.

Explanation:

At low O₂ pressure, oxyhaemoglobin dissociates into oxygen and deoxyhaemoglobin in tissues. When tissue oxygen pressure is high, oxyhaemoglobin will not dissociate into O₂ and haemoglobin and will not return CO₂ to the lungs.
