The Agawam High School band is playing some lively marches while the coaches are giving pep talks to their respective football squads. Although it is September, it is unseasonably hot (88ºF/31ºC) and the band uniforms are wool. Suddenly, Harry the tuba player becomes light-headed and faints. Explain what happened.

- . Carbonic anhydrase of erythrocytes (M, 30,000) has one of the highest turnover numbers known. It catalyzes the reversible hydration of CO₂. H₂O + CO₂ H₂CO3 This is an important process in the transport of CO₂ from the tissues to the lungs. If 3 µg of pure carbonic anhydrase catalyzes the hydration of 0.10 g of CO₂ in 1 min at 37 °C at Vmax, what is the turnover number (kcat) of carbonic anhydrase?

- x The Bohr effect describes the impact of changes in serum pH and CO2 concentrations on the oxygen dissociation curve of hemoglobin. This effect is physiologically important because it allows the body to adapt to changing conditions and provide enough oxygen to different types of tissues. **Plot the curves of hemoglobin oxygen saturation for patients in conditions of acidosis (serum pH below 7.34) and alkalosis (serum pH higher than 7.45) and compare it to the one in normal conditions. ** **When tissues, such as muscle tissue, are performing large amounts of strenuous activity the increase in metabolic activity produces CO2 as waste. Once in the bloodstream the enzyme carbonic anhydrase speeds up the conversion of CO2 to bicarbonate and protons. How does this affect the release of oxygen to the tissues?** **2,3-bisphosphoglycerate is an allosteric inhibitor of oxygen binding to hemoglobin. Acclimatization to high altitude involves numerous physiological and biochemical changes,…arrow_forward5 Acid-base balance is regulated by a system of buffers.
