Answer 1

Answer:

co(B) makes the most stable combination with haemoglobin of red blood

Answer 2

Answer:

The CO –gas  makes the most stable combination with the haemoglobin of red blood cell (HbCO).

Explanation:

• The Carbon monoxide reacts to haemoglobin when breathing.
• It connects so heavily that it also prevents oxygen from binding.
• Over a long time period, it binds to all the haemoglobin in human body does not carry the oxygen it will leads to insufficient enough oxygen blood anymore.

Example: The carboxy haemoglobin makes less oxygen carries to the heart during respiration.
