alleryRoughly how many times more readily does haemoglobin bind CO than O2?
AAbout 2 times
BAbout 2100 times
CAbout 21 times
DAbout 210 times
Answer & Solution
Correct answer: D. About 210 times
Haemoglobin binds carbon monoxide about 210 times more readily than oxygen, so CO displaces O2 even at tiny levels.
