( a ) (i) This curve is called the Oxygen dissociation curve. (ii) Saturation of haemoglobin with CO2 is plotted against the pO2. (iii) It is highly useful in studying the effect of factors like pCO2, H+ concentration, etc., on binding of O2 with hemoglobin.
( b ) (i) This curve is called the Oxygen dissociation curve. (ii) Saturation of haemoglobin with O2 is plotted against the pO2. (iii) It is highly useful in studying the effect of factors like pCO2, H+ concentration, etc., on binding of O2 with hemoglobin.
( c ) (i) This curve is called the Oxygen association curve. (ii) A sigmoid curve is obtained when percentage saturation of haemoglobin with CO2 is plotted against the pO2. (iii) It is highly useful in studying the effect of factors like pCO2, H+ concentration, etc., on binding of O2 with hemoglobin.
( d ) (i) This curve is called the Oxygen dissociation curve. (ii) A sigmoid curve is obtained when percentage saturation of haemoglobin with O2 is plotted against the pO2. (iii) It is highly useful in studying the effect of factors like pCO2, H+ concentration, etc., on binding of O2 with hemoglobin.

1 Answer

(D) is the right answer.

A sigmoid curve is obtained when percentage saturation of haemoglobin with O2 is plotted against the pO2. This curve is called the Oxygen dissociation curve and is highly useful in studying the effect of factors like pCO2, H+ concentration, etc., on binding of O2 with hemoglobin
