Biology Tests Respiratory System Physiology Test 03 Online Preparation 0 Respiratory System Physiology Test 03 Online Preparation 1. Which of these is termed Bohr effect?A. None of theseB. Deoxygenation of oxyhaemoglobin is directly proportional to PCO2 C. Oxygen carrying capacity of whole blood is higher than plasmaD. Increase in CO2 concentration decreases O2 affinity of Hb Loading... 2. A person on inhaling air having well as carbon monoxide suffers from suffocation because?A. Hb of blood combines with CO instead of O2 and the product cannot dissociate B. CO reacts with O2 reducing its percentage in the air C. CO affects diaphragm and internal muscles D. CO affects nerves of the lungs Loading... 3. The atmosphere of industrial area loaded with chimines is considered harmful to health because?A. The air has very low percentage of oxygenB. There is more water vapour which makes breathing difficult C. There is carbonmomonoxide which can bind with Hb 230 times more than oxygen and its pressure of about 0.7 mm Hg is lethal D. There is more and more carbondioxide Loading... 4. Haldane effect states that?A. Oxyhaemoglobin behaves as a strong acid so more and more amount of it formed releases more and more H+ions B. Increase the oxygen affinity of haemoglobin C. Deoxygenation of oxyhaemoglobin is directly proportional to PCO2 D. None of these facts Loading... 5. A catabolic process by which the chemical degradation of body fuel substances is done to obtain energy is called?A. External respiration B. Metabolism C. Tissue respiration D. None of these Loading... 6. Deoxygenation of oxyhaemoglobin is?A. Directly proportional to PO2 B. Inversely proportional to PO2C. Directly proportional to blood PCO2 D. Inversely proportional to blood PCO2 Loading... 7. Oxygen capacity of haemoglobin is?A. None of theseB. The amount of oxygen which is present in blood of alveolar circulation C. The amount of oxygen which 1 gm of haemoglobin can bind D. The amount of oxygen which haemoglobin exchanges with similar amount of carbondioxide Loading... 8. During one circuit of blood from lungs to the tissue and back through circulatory system the percentages of haemoglobin giving up its oxygen to tissues is?A. 75% B. 25% C. 50% D. 100% Loading... 9. How much oxygen binds with 1 gm of haemoglobin in normal state?A. 1.0gm B. 0.5ml C. 0.75ml D. 1.34gm Loading... 10. Which of these facts sugests that oxygen is transported from lungs to the tissues combined with haemoglobin rather than dissolved in blood plasma?A.
