Which enzyme(s), in nucleotide biosynthesis pathways, use(s) a substrate channeling mechanism?
A) carbamoyl phosphate synthetase
B) nucleoside monophosphate kinase
C) glutamine phosphoribosyl amidotransferase
D) aspartate transcarbamoylase
E) carbamoyl phosphate synthetase and glutamine phosphoribosyl amidotransferase

Question

Quizplus · Accepted Answer

Carbamoyl phosphate synthetase and glutamine phosphoribosyl amidotransferase use substrate channeling mechanisms, where intermediates are directly transferred from one active site to another within the same enzyme complex, enhancing the efficiency of the biosynthesis process.
