Most of the carbon dioxide in the blood is transported:

A) by being dissolved in plasma.
B) as bicarbonate ions.
C) by hemoglobin.
D) as carbonic anhydrase.
E) as carbonic acid.

Carbon Dioxide

It's a transparent, unscented gas formed through the burning of carbon-containing compounds and the act of breathing, which is assimilated by plants in the photosynthesis process.

Bicarbonate Ions

Bicarbonate ions (HCO3-) act as a buffer in biological systems, helping to maintain pH balance in blood and other bodily fluids.

Carbonic Anhydrase

An enzyme that catalyzes the conversion of carbon dioxide and water into carbonic acid, playing a vital role in respiratory gas exchange and pH balance.
