A) carbonate
B) carboxy haemoglobin
C) bicarbonate
D) \[C{{O}_{2}}\] as such
Correct Answer: C
Solution :
In dissolved state 7% of \[C{{O}_{2}}\] gets dissolved in the blood plasma and is carried in solution to lungs or about 0.3 ml of \[C{{O}_{2}}\] is transported per 100 ml of blood in dissolved state in blood plasma. In the form of bicarbonate About 70% of \[C{{O}_{2}}\] (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 \[({{H}_{2}}C{{O}_{3}})\]. As carbaminohaemoglobin About 23% of \[C{{O}_{2}}\] is transported in combination with haemoglobin and plasma proteins. \[C{{O}_{3}}\] reacts directly with amine radicals (NH2) of haemoglobin to form an unstable compound carbamino-haemoglobin \[(Hb.C{{O}_{2}})\] Sodium bicarbonate acts as buffer of blood.You need to login to perform this action.
