In blood, CO ₂ in transported majorly as

Options

  1. Asodium carbonate
  2. Bcarboxyhaemoglobin
  3. Cbicarbonate
  4. DCO ₂ as such

Correct answer

C. bicarbonate

Step-by-step solution

In dissolved state 7 % of CO ₂ gets dissolved in the blood plasma and is carried in solution to lungs or about 0.3 mL of CO ₂ is transported per 100 mL of blood in dissolved state in blood plasma. In the form of bicarbonate about 70 % of CO ₂ (about 2.5 mL per 100 mL of blood) received by blood from tissues, enters the RBCs where it reacts with water to form carbonic acid ( H ₂ CO ₃ ) . As carbaminohaemoglobin about 23 % of CO ₂ is transported in combination with haemoglobin and plasma proteins. CO ₂ reacts directl
