Tobacco smoke contains carbon monoxide. Explain how carbon monoxide affects a persons ability to exercise.
Carbon monoxide is a poisonous gas. It binds to haemoglobin in red blood cells irreversibly. This means that less oxygen can be carried by red blood cells. As oxygen delivery decreases to muscles and so less energy is available to the individual for exercise.
