Summary Introduction

To explain:

The reason of CO being a deadly gas irrespective of the fact that it is a colorless, odorless gas found in furnace and automobile engine exhaust and cigarette smoke. CO binds to hemoglobin 210 times more tightly than does O2. CO also bonds with an electron transport protein and disrupts cellular respiration.

Concept introduction:

Carbon monoxide is an odorless, tasteless and colorless gas with less density than air. It consists of one atom of carbon and one atom of oxygen connected with a triple bond with a molecular mass of 28.01 g/mol.

Blurred answer
Students have asked these similar questions
Which of the following is TRUE of carbon monoxide poisoning? Group of answer choices choose one answer Carbon monoxide is toxic because it binds more readily to hemoglobin than oxygen, thereby decreasing the oxygen carrying capacity of blood. As the carbon dioxide content of blood increases, a phenomenon known as the Haldane effect converts the excess carbon dioxide to carbon monoxide until it reaches toxic levels. Carbon monoxide is toxic because it readily picks up oxygen to produce carbon dioxide, causing acidosis and eventual death. Carbon monoxide causes the carbamino effect where carbon dioxide is stripped of an oxygen, producing carbon monoxide.
Why is carbon monoxidetoxic for humans?
The enzymes catalase combine two hydrogen peroxide molecules(H20+H2O) to make two molecules of water 2H2O). A gas forms. What is the gas and how do you know this?
