Identify the wrong statement with reference to transport of oxygen.
(1) Low pCO2 in alveoli favours the formation of oxyhaemoglobin.
(2) Binding of oxygen with haemoglobin is mainly related to partial pressure of O2 .
(3) Partial pressure of CO2 can interfere with O2 binding with haemoglobin.
(4) Higher H+ conc. in alveoli favours the formation of oxyhaemoglobin
