1.	Living in the atmosphere of CO is dangerous because it.(a) Reduces organic matter of tissues (b) Dries up the blood (c) Combined with O2 present inside to form CO2 (d) Combines with haemoglobin and makes it incapable of absorbing oxygen
Answer» (d) Combines with haemoglobin and makes it incapable of absorbing oxygen. Explanation: When CO is not ventilated it binds to haemoglobin, which is the principal oxygen-carrying compound in blood; this produces a compound known as carboxyhaemoglobin. The traditional belief is that carbon monoxide toxicity arises from the formation of carboxyhaemoglobin, which decreases the oxygen-carrying capacity of the blood and inhibits the transport, delivery, and utilization of oxygen by the body.
