Carbon monoxide is toxic because….
...it binds strongly to the iron atom in haemoglobin, preventing the blood from carrying oxygen.
.…it causes toxic levels of carbonic acid, lowering the pH of the blood.
.…binds to a cytochrome-P450 enzyme, inhibiting metabolism of common toxins.
.…it causes constriction of airways in the lungs, restricting oxygen intake.
