Final answer:
Carbon dioxide in the blood is mostly transported by dissolving in the blood plasma. A high level of carbon dioxide due to conditions like COPD can result in respiratory acidosis. Hemoglobin primarily binds to oxygen, not carbon dioxide.
Explanation:
The majority of carbon dioxide in the blood is transported by: dissolution in the blood. It dissolves directly in the plasma of the blood in the form of bicarbonate ions.
When there is too much carbon dioxide in the blood due to a condition like COPD, it can lead to respiratory acidosis.
Hemoglobin does not directly bind to carbon dioxide for transport, as it mainly binds to oxygen.
