transport.

is neutralized by NaCO₃
(d) it is continuously diffused through tissues
and is not allowed to accumulate

Answer 2

Answer is option "b"

Explanation:

• Although much carbon dioxide is carried in the blood, yet blood does not become acidic. It is due to carbon dioxide  transport and buffering action of blood.
• The main buffer present in the blood is bicarbonate (which is formed during transport in the blood). Bicarbonates exist in equilibrium with carbonic acid which in turn can be converted to  carbon dioxide and water.
• So, the right answer is option b "blood buffers play an important role in $CO_{2}$  transport."
