NEET Botany Respiration In Plants Class 11 Questions

How many statements are not correct for transport of oxygen? (i) About 97 per cent of O₂ is transported by RBCs in the blood. (ii) Each haemoglobin molecule can carry a maximum of four molecules of O₂ (iii) Binding of oxygen with haemoglobin is primarily related to partial pressure of O₂. (iv) Partial pressure of CO₂, hydrogen ion concentration and temperature are the other factors which can interfere with this binding. (v) A sigmoid curve is obtained when percentage saturation of haemoglobin with O₂ is plotted against the PO₂ (vi) Every 100 of oxygenated blood can deliver around 5 ml of CO₂ to the lungs under normal physiological conditions.
