How many PRPP are required to synthesize two UMP and two CTP from carbamoyl aspartate?
A) 0
B) 2
C) 4
D) 8

Question

Quizplus · Accepted Answer

Carbamoyl aspartate is a precursor molecule for both UMP and CTP synthesis. The conversion of carbamoyl aspartate to UMP requires two molecules of PRPP, while the conversion to CTP requires four molecules of PRPP. Therefore, a total of 4 molecules of PRPP are required to synthesize two UMP and two CTP from carbamoyl aspartate.
