Question

Approximately what percentage of CO2 is transported via the cardiovascular system bound to hemoglobin as carbaminohemoglobin?

A. 10%

B. 20%

C. 30%

D. 40%

Answer 1

Approximately 20% of carbon dioxide is transported via the cardiovascular system bound to hemoglobin as carbaminohemoglobin. The majority of carbon dioxide is transported as bicarbonate ions, while a smaller portion remains dissolved in plasma.

Step-by-step explanation:

Approximately 20% of carbon dioxide is transported via the cardiovascular system bound to hemoglobin as carbaminohemoglobin.

When carbon dioxide binds to hemoglobin, it forms carbaminohemoglobin, which can be reversed when it reaches the lungs, allowing carbon dioxide to be expelled from the body. The majority of carbon dioxide (about 70%) is transported as bicarbonate ions, while a smaller portion remains dissolved in plasma.
