Which of these is a direct fuel for the urea cycle?
B)glutamate 
C)carbamoyl phosphate 
D)pyruvate

Quizplus · Accepted Answer

Carbamoyl phosphate is a direct fuel for the urea cycle, as it is the first intermediate in the cycle and combines with ornithine to form citrulline. Glutamate is an amino acid that can be converted into other intermediates in the cycle, but it is not a direct fuel. Pyruvate is not a part of the urea cycle at all.
