All of the following are true of the isohydric mechanism EXCEPT: A) it results in no change in intra-erythrocyte pH B) it is responsible for accommodating 40% of the hydrogen ions generated during CO₂ transport C) it is linked to oxygen uptake and release D) it is responsible for the chloride shift

Question

Quizplus · Accepted Answer

The isohydric mechanism is responsible for regulating pH changes during CO2 transport by controlling the release and uptake of hydrogen ions and bicarbonate ions by erythrocytes. It is not responsible for the chloride shift, which refers to the exchange of chloride ions and bicarbonate ions across the erythrocyte membrane that occurs during gas exchange in the lungs and tissues. Therefore, choice D is incorrect. Choices A, B, and C are true statements about the isohydric mechanism.
