Question

Explain the methods of release of carbon dioxide to the atmosphere from the cell during the process of transportation in humans

Answer 1

Answer:

co2

Explanation:

* co2 can be released through our body vio breathing during expiration.

* carbon dioxide is released when pressure in the lungs in higher than the atmospheric pressure

Answer 2

Answer:

Carbon dioxide is removed through three methods dissolution into the blood, binding itself to haemoglobin or carried as bicarbonate ion.

Explanation:

The carbon dioxide is transported in three ways through blood.

• It is dissolved directly in the blood,

• It is bound to plasma proteins or even haemoglobin, forming carbaminohaemoglobin. This is a reversible process. 10% of CO₂ is expelled from the body.  

• Majority of CO₂  travel as a part of the bicarbonate buffer system. CO₂ diffuses in RBC, with the help of carbonic anhydrase  CO₂ is converted into H₂CO₃ (carbonic acid). The carbonic acid is again converted in CO₂ and expelled out through the lungs during exhalation.

Hence, The most common way to transport the carbon dioxide into the atmosphere from the cell during the bicarbonate system through which 85% of CO₂ is expelled out.
