If the pH of the blood were to rise and the blood become less acidic, what affect would this have?
a. The red blood cells would secrete carbonic anhydrase.
b. The blood would carry more CO2.
c. Hemoglobin would release O2 more readily.
d. Hemoglobin would be more likely to bind O2.
e. Heme groups would bind more tightly to the globin.
D; If a drop in pH causes the hemoglobin to click into an oxygen-releasing conformation, it follows that a rise will make it more likely that the hemoglobin will return to a state where it binds oxygen more readily. Choice a is wrong because healthy red blood cells do not release proteins. Choice b is wrong because blood at a higher pH has less CO2; moreover this choice confuses cause and effect.
