O_(2) binds with haemoglobin od RBC to form

Given below are assertion and reason. Point out if both are true with reason being correct explanation (A), Both are true but reason is not correct expalantion (B), assertion is true but reason is wrong ( C), and both are wrong (D). Assertion. Smoking causes oxygen deficiency in the body Reason: Carbon monoxide when inhaled while smoking, combines with haemoglobin to form chemically stable compound

Assertion :- RNA is less stable then DNA. Reason : In RNA'2 - OH group present on every nucleotide.

Assertion : The presence of CO reduces the amount of haemoglobin available in the blood for carrying oxygen to the body cells. Reason : CO combines with haemoglobin about 200 times less easily than oxygen to form complex.

In the following question a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as : Assertion (A): Smoking increases the carbon monoxide (CO) content in the blood which has greater affinity to haemoglobin than oxygen. Reason (R) CO forms a stable bond with haemoglobin and does not allow binding of oxygen. It reduces concentration of haem bound oxygen and causes oxygen deficiency in the body.

Assertion are conformers. Reason:- First is less stable than second.

As compared to CO_(2) carbon monoxide binds to haemoglobin
