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

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
