1. Considering a patient with severe pneumonia, resulting in impaired exchange of O2 and CO2 between the air and blood in the lungs? Would the oxygen (O2) levels in the blood be: (a) Normal (b) below normal (c) elevated 2. With respect to item #1, would the CO2 levels in the same patient’s blood be ? (a) Normal (b) below normal (c) elevated 3. With respect to item #1 and 2, assuming that other compensatory measures have not yet had time to act, what would happen to the patient’s blood considering thatCO2 reacts with water to form carbonic acid? (a) have a normal pH (b) be too acidic (c) not be acidic enough (that is, be too alkaline)

(a) The partial pressure of CO2 in the lungs can be varied rapidly by the rate and depth of breathing. For example, a common remedy to alleviate hiccups is to increase the concentration of CO2 in the lungs. This can be achieved by holding one’s breath, by very slow and shallow breathing (hypoventilation), or by breathing in and out of a paper bag.Under such conditions, pCO2 in the air space of the lungs rises above normal. Qualitatively explain the effect of these procedures on the blood pH.(b) A common practice of competitive short-distance runners is to breathe rapidly and deeply (hyperventilate) for about half a minute to remove CO2from their lungs just before the race begins. Blood pH may rise to 7.60. Explain why the blood pH increases.(c) During a short-distance run, the muscles produce a large amount of lactic acid (CH2CH(OH)COOH; K2 = 1.38 × 10 –4 M) from their glucose stores. Why might hyperventilation before a dash be useful?

Each of the following statements briefly describes one of Hb an allosteric interactions. Which of the statements below are false? A drop in the [H+] of blood plasma would lead to a decrease Hb affinity for O₂. An increase in the partial pressure of CO₂ in the tissues would lead to a decrease Hb affinity for O₂- If you inhaled CO for an extended period of time, at partial pressures 1000 fold higher than normal indoor atmospheric pressure, your body would have a difficult time delivering oxygen to your tissues. When the partial pressure of oxygen is low within the atmosphere, your body responds by increasing the biological activity of Hb's negative effectors.
