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?

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.
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.
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.
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.
None of the above
