Continue to draw citric acid cycle intermediates up until a 14C-labeled CO2 molecule is generated by the cycle. How many turns of the citric acid cycle must be made before 14CO2 is released? Which enzymatic reaction in the citric acid cycle first catalyzes the release of 14CO2? The 14C-labled CO2 molecule is from the orginal Carbon #2 carbon on the frutose molecule.

Kornberg and his colleagues incubated soluble extracts of E.coli. with a mixture of dATP, dTTP, dGTP, and dCTP, all labeled with 32P in the α phosphate group. After a time, the incubation mixture was treated with trichloroacetic acid which precipitates the DNA but not the nucleotide precursors. The precipitate was collected and the extent of precursor incorporation into DNA was determined from the amount of radioactivity present in the precipitate. a. If any one of the 4 nucleotide precursors were...

The effect of inorganic phosphate on the activity of the citric acid cycle can be studied in mitochondrial extracts by monitoring the rate of CO2 production. a. Why is the citric acid cycle dependent upon inorganic phosphate? b. Acetyl CoA is added to a rat liver mitochondrial extract containing excess NAD+, FAD, and GDP. The rate of CO2 production increases and then levels off very quickly; the addition of addition acetyl CoA has no effect. Explain why CO2 production begins...
