NEET Biology question
Which of the following statements are true/false? I. The blood transports carbon dioxide comparatively easily because of its highest solubility. II. Approximately 8.9% of carbon dioxide is transported being dissolved in the plasma of blood. III. The carbon dioxide produced by the tissues, diffuses passively into the blood stream and passes into red blood corpuscles and reacts with water to form HCO. IV. The oxyhaemoglobin (HbO) of the erythrocytes is basic. V. The chloride ions diffuse from plasma into the erythrocytes to maintain ionic balance.
Solution
CO is indeed transported more easily than O owing to its high solubility (I true), only about 7% (not 8.9%) of CO is carried dissolved in plasma (II false), CO does diffuse into RBCs and combine with water to form carbonic acid (III true),
