Question

______ is a product of incomplete combustion of fuels. It reduces the oxygen carrying capacity of blood.

Answer 1

Carbon monoxide is a product of incomplete combustion of fuels. It reduces the oxygen carrying capacity of blood.

Explanation:

Carbon monoxide binds with hemoglobin in the blood more strongly than oxygen does, forming carboxyhemoglobin. This reduces the blood’s ability to carry oxygen to body tissues, leading to oxygen deficiency. It is a major toxic pollutant mainly released from incomplete combustion in vehicle engines, industrial processes, and burning of fossil fuels.
