Increased acidity at the tissue cells stimulates increased dissociation of oxyhaemoglobin.

Question

Quizplus · Accepted Answer

When the tissue cells become more acidic, there is an increased dissociation of oxyhemoglobin. This is known as the Bohr effect, which is an important physiological mechanism that helps to deliver oxygen to the tissues where it is needed. As the acidity increases, the affinity between the haemoglobin molecule and the oxygen molecule decreases, allowing the oxygen to be released more easily. This process ensures that the tissues receive the oxygen they need, even when they are under stress or working hard.
