Question

Carbon monoxide in vehicle exhaust causes
(a) Increased oxygen carrying capacity of RBCs
(b) Reduced Nitrogen carrying capacity of RBCs
(C) Reduced oxygen carrying capacity of RBCs
(d) Reduced carbon carrying capacity of RBCs​

Answer 1

Answer:

options C is the correct answer of following question.

Answer 2

Answer:

carbon monoxide in vehicle exhausts reduces the oxygen carrying capacity of RBCs

Explanation:

this is because when carbon monoxide and oxygen both are available to rbcs then the rbcs will bind 200 times faster with carbon monoxide than oxygen, thus forming carboxyhaemoglobin rather than oxyhaemoglobin. this carboxyhaemoglobin reduces the oxygen carrying capacity of rbcs(since rbcs contain haemoglobin,a red-coloured protein).
