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

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
