Unformatted text preview: succinyl CoA 28. a) +0.123 V b) -23.74 kJ/mole 29. a) Tissues generate carbon dioxide, which combines with water to make H 2 CO 3 . The H 2 CO 3 in turn dissociates to give H + + HCO 3-. The H + generated in the formation of bicarbonate then combines with HbO 2 to give HHb + O 2 . The foregoing equilibria, which constitute the Bohr effect, explains how carbon dioxide is transported as biocarbonate from the tissues to the lungs. In the lungs these processes reverse, and carbon dioxide is once again formed. The major carbon dioxide-producing reactions are the pyruvate dehydrogenase reaction, and the two decarboxylation steps of the TCA cycle, that involving isocitrate dehydrogenase, and that involving a-ketoglutarate dehydrogenase. 30. See the answer key for examination 2 in the spring of 2007. It is on the course website....
