Suppose that in the citric acid cycle, oxalacetate is labeled with 14C in the carboxyl carbon farthest from the keto group. Where would you expect to find the 14C label when alpha-ketoglutarate is converted to succinate?

a. All of the alpha-ketoglutarate formed would contain radioactive 14C, none of the succinate would contain 14C, and none of the carbon dioxide would contain 14C.
b. Half of the alpha-ketoglutarate formed would contain radioactive 14C, half of the succinate would contain 14C, and half of the carbon dioxide released would contain 14C.
c. None of the alpha-ketoglutarate formed would contain radioactive 14C, all of the succinate would contain 14C, and all of the carbon dioxide released would contain 14C.
d. All of the alpha-ketoglutarate formed would contain radioactive 14C, none of the succinate would contain 14C, and all of the carbon dioxide released would contain 14C.
e. None of the above
