What factors influence the dissociation of oxyhaemoglobin as explained by the Bohr’s effect?
Low temperature and high pH
High temperature and low pH
High temperature and high pH
Low temperature and low pH
The dissociation of oxyhaemoglobin depends on the temperature and pH of the cell, as explained through the Bohr’s effect. At the tissue level, high temperature and low pH favour the dissociation of oxygen from the haemoglobin, while low temperature and high pH oppose it. This is because high temperature and low pH indicate a higher metabolic activity in the tissues, which requires more oxygen for respiration.
Option b is the correct answer.
