A) xanthosine- -monophosphate
B) adenylosuccinate
C) 5-phosphoriboxylamine
D) 5-aminoimidazole ribonucleotide

D) 5-aminoimidazole ribonucleotide

Quizplus · Accepted Answer

Xanthosine monophosphate is an intermediate in the conversion of IMP to GMP, but it is not involved in the conversion of IMP to AMP. Therefore, A is the correct answer. Adenylosuccinate, 5-phosphoriboxylamine, and 5-aminoimidazole ribonucleotide are all intermediates in both pathways.
