Question 47
F

Carbon monoxide binds to haemoglobin much more strongly than oxygen does, and it does not come off again easily. Which statement explains why breathing in carbon monoxide is dangerous?

A

Fewer red blood cells are made, so less haemoglobin is available

B

Less oxygen is carried, so cells carry out less aerobic respiration

C

More platelets are made, so the blood clots inside the vessels

D

Less plasma is made, so fewer dissolved substances are carried
