Question

According to Heldane effect how oxyhaemoglobin behaves:
(a) It act as powerful base so reaction with CO2 reduces
(b) It act as strong base so reaction with CO2 increase
(c) Oxyhaemoglobin act as strong acid so association with CO2 reduces
(d) Oxyhaemoglobin act as strong acid so association with CO2 increase

Answer 1

According to Haldane effect oxy-haemoglobin (c) acts as strong acid so association with CO2 reduces.  

Oxygenated haemoglobin is a stronger acid in comparison to deoxygenated haemoglobin, which is a base.

Now, Haemoglobin accepts H+ when co2 is the more effective constituent present at the level of tissues, and releases H+ when o2 is the more effective constituent present at the level of lungs.

The co2 thus formed after this gets removed in the lungs.
