Which of the following reactions takes place in red blood cells in the capillaries surrounding the cells of active tissues?

Question

Quizplus · Accepted Answer

The reaction shown in choice B is the conversion of carbon dioxide and water into carbonic acid, which then dissociates into bicarbonate ions and hydrogen ions. This reaction occurs in red blood cells in the capillaries surrounding the cells of active tissues, where there is high oxygen demand and high carbon dioxide production. The bicarbonate ions are transported out of the red blood cells and into the plasma, while the hydrogen ions combine with hemoglobin in the red blood cells. This reaction is important for regulating pH and ensuring that oxygen can be delivered to the active tissues.
