Carbon monoxide (CO) is an odorless, colorless, and tasteless gas that is toxic in high enough concentrations. It can be a by-product of burning fossil fuels. CO binds irreversibly to the protein (hemoglobin) that transports O2 throughout your bloodstream. As you are exposed to high amounts of CO over a period of time your available hemoglobin becomes unable to bind to O2 because it is bound to CO. In your own words, explain what would happen to cellular respiration and what overall effect this would have on the organism.
